    DISCUSSION

    1. Question: I get the error message, "PLAY32 caused an invalid page fault". What is wrong?

    Answer: This normally occurs due to a bad download. You will need to download and install QuickTime for Windows again. Be sure to perform an uninstall prior to reinstalling.

    You can also try installing and skipping the search for old versions. Occasionally this can also work, if you have uninstalled all previous version.

    2. Question: I get the error message, "Program error. Your program is making an invalid dynamic link library call to a .dll file. Your program will close". What is wrong?

    Answer: The error is caused by having mixed versions of QuickTime on your system. The software gets a response from more than one version of QuickTime--hence the error. For example, in the early days games put versions of QuickTime into the game folder, allowing for multiple copies and versions to be installed on your system. Now QuickTime is only installed in one location by developers.

    Possible Solutions:

    a) The easiest solution is to uninstall the program and then do a fresh install. When running the fresh install be sure to say yes when asked if you want to delete all other versions of QuickTime on your system. For Windows 3.x (16 bit) you will need to do a manual uninstall. See Uninstall 3.1 later in this document.

    b) Check your SYTEM.INI file for the line dci=rfmdci . If it is there, comment it out. The comment about dci=rfmdci is a reference to dci services by the video card and has been found to occasionally cause issues.

    3. Question: How can I check to see if QuickTime is installed and what version number of QuickTime I have installed?

    Answer: Open your control panels folder and look for the control panel named "QuickTime 32" (or "QuickTime"). If it is not there, QuickTime is not installed. If the control panel is there, open it. The version will be in the upper right hand corner of the Control Panel.

    4. Question: I am not sure I installed everything necessary to use QuickTime on (and off) the Internet. What do I need and how can I check to make sure everything is installed?

    Answer: To use QuickTime on (and off) the Internet you must have the appropriate version (2.1.2.59) and flavor (16 or 32 bit) of QuickTime for Windows installed. In addition, you must have the appropriate version of the QuickTime Plug-In (1.1.1) and the QuickTime VR Component (1.03).

    Verify and/or try the following:
    • Verify that you downloaded the "easy download" from Apple's QuickTime site. You can find QuickTime software at http://www.apple.com/quicktime/
    • Was this the first time you installed QuickTime For Windows on your system? If it was not, did you first perform an uninstall of the old version? Did you manually remove the old plug-in file in the Plug-In folder? Did you manually remove the old QTVR file from the windows/system directory?
    • Verify that you double-clicked on the downloaded file and that it installed QuickTime for Windows, NPQTW32.DLL into the plug-in folder and QTWVR.QTC into the Windows/System directory.
    • Verify that you have only one QuickTime Plug-In in your plug-in folder. Use either the Start...Find...files or the folders...command option, and type "NPQTW32.DLL" into the find window. It should find and list one file named NPQTW32 in your Netscape Plug-ins folder. Click the right mouse button over the icon for this file in the list and select "properties" from the popup. Next, click the "Version" tab in the Properties window that is displayed. It should say File Version: 1.1.1.0. You should have just one QuickTIme Plug-In installed.
    • Verify that QuickTime for Windows was installed correctly. A sure way to tell would be to open your control panels and look for a control panel named "QuickTime 32". If the control panel is not there, then you have not installed QuickTime by double-clicking on QT32INST.EXE. If the control panel is there, take the opportunity to click the "Verify Setup" button to make sure all the files are installed properly.
    • Does the sample movie included with QuickTime run correctly?
    • Have you configured your browser to use the Plug-In?

    5. Question: I am having video issues. Also, I am having trouble with the control panel, and sometimes Movie Player locks up. Can you help?

    Answer: It could be that the default settings QuickTime chose when it looked at your hardware may be inappropriate, specifically for video. Verify and/or check the following:

    a) Click the "Verify Setup" on the control panel to make sure all the files are there. Then you can try choosing "More" and scrutinizing the video and audio settings. Continue to the next step if you cannot access the Control Panel.

    b) You can hand correct the QTW.INI file. The QTW.INI file is located in your Windows directory. If it is not there you can simply create one by using a text editor such as Notepad. Try the following:

    [Video]
    Optimize=Driver

    [Video 32]
    Optimize=Driver

    If it works go to step d. If not, continue with step c.

    c) You can hand correct the QTW.INI file, using a different set of parameters than those in step b above. The QTW.INI file is located in your Windows directory. If it is not there you can simply create one by using a text editor such as Notepad. Try the following:

    [Video]
    Optimize=BMP
    [Video 32]
    Optimize=BMP

    If it works go to step d.

    d) If things work, then the driver for your video card has compatibility issues with QuickTime. Many times the video card manufacturer's web site will have newer versions of their drivers. These newer versions may solve the compatibility issue with QuickTime.

    If you find a newer driver, try installing it and then selecting "Video Driver" under the optimization section of the QuickTime control panel.

    6. Question: The movie that I downloaded will not play. Why?

    Answer: There are a couple of reasons why a downloaded movie will not play.
    • The movie was encoded with a type that QuickTime does not recognize. QuickTime for Windows currently recognizes only .mov or .moov files.
    • The file was not saved for cross-platform viewing. This can be done on a Macintosh using MoviePlayer.
    • The file is corrupted.

    7. Question: I get the error message, "Old Version of QuickTime" or "Invalid Dynamic Link to *.DLL". What is wrong?

    Answer: Sometimes other applications (such as games) install QuickTime on the hard drive in the application's directory. This could be confusing Netscape Navigator and the plug-in into thinking it is an old version of QuickTime.

    To correct the issue for Windows 3.1:
    • Uninstall QTW 3.1 by hand to ensure all items are getting removed. Once this is accomplished, reinstall version 2.1.2 of QuickTime for Windows. (Instructions for uninstalling are at the end of this article).

    To correct the issue under Windows 95:
    • Install QuickTime Windows 95 2.1.2.59 and answer yes when asked if you wish to delete all old versions.

    Also check your SYSTEM.INI file for the line:

    dci=rfmdci

    If it is there, comment it out by placing a semi-colon at the beginning of the line. (The entry is a reference to dci services by the video card and has been found to occasionally cause issues.)

    8. Quest ion: QuickTime VR will not play. What is wrong?

    Answer: Verify that the file named QTVR@.QTC (16-bit) or QTVRW32.QTC (32-bit) is in the Windows\system directory.

    If the file is there, then other possibilities include:
    • The VR movie was not flattened for cross-platform playing.
    • JPEG compression was used when creating the VR movie.

    If the VR movie was not flattened for cross-platform play, open it up in Movie Player on a Macintosh, choose "Save As..." from the File menu. Click on the Flatten button and the Make playable on Non-Apple computers check box, and then save the movie.

    If JPEG compression was used, the only way to get it to display correctly with the 1.0.3 components file is to make sure you are in 24-bit color on your PC.

    9. Question: My system appears to have a conflict between QuickTime for Windows and OLE. How can I fix this?

    Answer: When the QuickTIme is installed on Windows 3.1 occasionally the registry file gets confused. This happens with certain versions of OLE.

    To correct the issue:
    a) Find the file reg.dat. Delete the file.
    b) Find the regedit.exe file. Double-click on the file to open it.
    c) Close the file.
    d) Reboot the system and try QuickTime again.

    If this does not correct the issue you will need to reinstall Windows 3.1.

    10. Question: I am encountering Trumpet Winsock issues with QuickTime. I am, however, able to play QuickTime movies stored on my hard drive using Movie Player. What is wrong?

    Answer: There are 16-bit and 32-bit versions of Trumpet Winsock.

    If the 16-bit version is being used with Windows 95, be aware that this is not a configuration that was tested. In any event, the system should be set up with either ALL 16-bit or 32-bit components (QTW, QTVR, Plugin, Browser, Winsock). Remember, no mix 'n' match!

    Trumpet Winsock is not recommended for use with Windows 95. We recommend you use the dial-up software that is shipped with Windows 95.

    11. Question: I am an America Online user and I am having issues with QuickTime under Windows 95. NPQTW32.DLL, NPAUDIO.DLL, NPNUL16.DLL, and NPAVI16.DLL are the only files in my plug-in directory. I assume that there are different "flavors" here but that I am only running one at a time. What is wrong?

    Answer: The issue is likely with the 16- versus 32-bit "flavors" that you are running. America Online, the Browser, and QuickTime all have to be the same to work. Windows 95 can run either 16- or 32-bit versions. Verify that everything (including any plug-ins you are using) is the same flavor. Then try again.

    12. Question: Can you help me with my Internet browser configuration to be sure everything is correctly configured?

    Answer: All the browsers that support the QuickTime Plug-In are designed to recognize it automatically and use it to play back those media types that QuickTime supports. However, it is always good practive to verify the setup with the browser you are using.

    First, make sure the file NPQTW32.DLL is in the plug-ins directory within the directory where the browser is. Verify that QuickTime for Windows 95 is installed by checking the Control Panels folder. Verify that QTVRW32.QTC is installed in the systems/windows directory.

    Note: Windows 95 does not let you see .DLL files by default. In order to view .DLL files in Windows 95, make sure you are in the directory window, then choose View from the Options menu and select "Show all files" in the Options dialog box.

    Follow the instructions in the sections below to make sure your browser is properly set up to use the QuickTime Plug-In.

    Netscape Navigator 3.x for Windows 95
    a) Open Netscape Navigator.

    b) Choose General Preferences from the Options menu, then click the Helpers tab.

    c) Scroll down through the list of file types and click the item "video/quicktime" to highlight it. The information that appears for this item should be the following:

    File/MIME Type: video
    Subtype: quicktime
    File Extensions: qt,mov,moov
    Action: Unknown

    If this information is missing or incorrect, click Create New Type. Then enter the information given above, or edit the existing information.

    d) Click OK.

    Internet Explorer 3.x for Windows 95/NT
    If the .DLL file is in the right location and you are still having issues, install the latest version of QuickTime for Windows. QuickTime software can be found at:

    http://www.apple.com/quicktime/

    13. Question: When using my browser, I sometimes get the error message, "Could not load plug-in 'QuickTime' for the MIME type'video/quicktime'". What is wrong?

    Answer: This can be caused by a number of things:
    • Does the movie sample included (with QuickTIme for Windows run within Movie Player? If it does not play the sample movie there is something wrong with the installation (of QuickTIme for Windows. Uninstall and then reinstall the application.
    • Does the issue occur with all movies you try to play or just a particular URL/site? If the issue occurs only with a particular site, it could be that the movie is not formatted correctly to play under Windows, or that the movie's QuickTime media type is not supported with Windows at this time.
    • Verify that the NPQTW32.DLL or NPQTW16.DLL file is in the plug-in folder for the browser you are using. You should have only one QuickTime Plug-In installed in the folder and only one flavor of the plug-in in the folder.
    • Verify that QTWVR32.QTC or QTVRW.QTC is in the windows/system directory.
    • Are all the "flavors" of your software the same? Windows 95 can run 16 or 32 bit applications, but your browser and QuickTime need to be either 16- or 32-bit. No mixing the "flavors"! This actually tends to be the issue more often than not.
    • Check your SYSTEM.INI file for the following line: dci=rfmdci. If it is there comment it out.
    • You could be low on memory if you have 16 megabytes of RAM or less and you are running Netscape Navigator.

    14. Question: While running the installer for QuickTIme for Windows v2.1, I get the error message, "An error occurred while updating .INI files." What is wrong?

    Answer: When reading or writing an INI file, the 16-bit Windows APIs in both Windows 3.1x and Windows 95 have a limit of 32K bytes. This creates an issue when using the 16-bit Windows APIs to modify an INI file when it is greater then 32K bytes. However, INI files are simple text files and there is a workaround to allow a file larger than 32K bytes.

    The INI file to be modified by the QuickTime Installer must be less than 32K bytes. In order to install, you must split the INI files, then install QuickTime, and then combine the INI files. We have used Microsoft Write in the example below.

    a) Find the INI files that are 32K bytes or more: SYSTEM.INI and/or WIN.INI

    b) Use MS Write to split the files:
      • OPEN the SYSTEM.INI or WIN.INI file.
      • PAGE DOWN to about 30 pages. IMPORTANT: The first 30 pages of the SYSTEM.INI file needs to contain the [mci] section.
      • Hold the SHIFT key while PAGE DOWN through the rest of the file. IMPORTANT: The first 30 pages of the WIN.INI, needs to contain the following sections: [Extensions],[mci extensions],[embedding].
      • Once selected CUT the selection.
      • Launch another MS Write document.
      • PASTE into the new MS Write.
      • SAVE AS SYSTEM.QTW
      • Click on the title bar of the first opened Write with the selection still there.
      • Delete the section by pressing the DEL key.
      • SAVE AS SYSTEM.INI or WIN.INI
      • Repeat for the WIN.INI if necessary.
      • Run the QTW installer.
      • Re-append the offending INI files.

    c) Use MS Write:
      • OPEN the SYSTEM.QTW or WIN.QTW
      • SELECT ALL -> COPY
      • OPEN the SYSTEM.INI or WIN.INI
      • PAGE DOWN to the end and -> PASTE.
      • SAVE
      • Delete SYSTEM.QTW or WIN.QTW
      • Exit and re-enter Windows.

    NOTE: Generally INI files are less than 32K bytes. If your INI files are larger than 32K you may have unused or outdated information. The procedure outlined above is the only one we are aware of at this time. Please call Microsoft if you require another method or further explanation.

    15. Question: I am running Windows 3.1 and I need to uninstall all of the QuickTime files. How do I do this?

    Answer: Here is a procedure:

    a) Find PLAYER.EXE and select it using File Manager.

    b) List items by date. All QuickTime files will cluster around the PLAYER.EXE. Delete the following:
      {Windows}\PLAYER.EXE
      {Windows}\VIEWER.EXE
      {Windows}\MCENU.HLP
      {Windows}\PLAYENU.DLL
      {Windows}\PLAYENU.HLP
      {Windows}\QTINSTAL.EXE
      {Windows}\READ_QTW.WRI
      {Windows}\SAMPLE.MOV
      {Windows}\VIEWENU.DLL
      {Windows}\VIEWENU.HLP

    c) Find ATIVIDEO.QTC and select it.

    d) List items by date. NOTE: all QuickTime files will be write protected. List names with detail and you will see the "r" for write protection.
      {Windows}\SYSTEM\*.QTC
      {Windows}\SYSTEM\MCIQTENU.DLL
      {Windows}\SYSTEM\MCIQTW.DRV
      {Windows}\SYSTEM\QTHNDLR.DLL
      {Windows}\SYSTEM\QTIM.DLL
      {Windows}\SYSTEM\QTIMCMGR.DLL
      {Windows}\SYSTEM\QTMOVIE.VBX
      {Windows}\SYSTEM\QTNOTIFY.EXE
      {Windows}\SYSTEM\QTOLE.DLL
      {Windows}\SYSTEM\QTPIC.VBX
      {Windows}\SYSTEM\QTW16.CPL
      {Windows}\SYSTEM\QTWCP.HL

    e) Launch Write.exe and open SYSTEM.INI
      • delete this line from the [mci] in the SYSTEM.INI file:
        QTWVIDEO={Windows' directory}\MCIQTW.DRV
      • delete these lines from the [Extensions] section in the WIN.INI file:
        mov={Windows' directory}\player.exe ^.mov
        pic={Windows' directory}\viewer.exe ^.pic
      • delete these lines from the [mci extensions] section in the WIN.INI file:
        mov=QTWVideo
        pic=QTWVideo
        jpg=QTWVideo
      • delete these two lines from the [embedding] section in the WIN.INI file:
        PlayerFrameClass=QuickTime Movie, QuickTime Movie,{Windows' dir}\Player.exe,picture
        ViewerFrameClass=QuickTime Picture, QuickTime Picture,{Windows' dir}\viewer.exe,picture

    f) Delete the Program Group:
      • select the QuickTime for Windows group icon and delete it.
