TOPIC

    I am installing QuickTime 3 for Windows. QuickTime 3 downloaded and de-archived properly, however during installation I receive the error: "Rundll. Errors loading C:\Windows\System\Quicktime.cpl." The installation will continue, but upon trying to use QuickTime, I receive the error: "QuickTime cannot find the file QuickTime.CPL. This file is required to run QuickTime."

DISCUSSION

    If the installation of QuickTime 3 progresses as far as encountering an error during installation, it is safe to assume that the QuickTime 3 Installer is not corrupt. An error received during installation usually indicates a software issue. The following steps may be applied to general QuickTime 3 installation issues, as well as for the error noted above.

    The QuickTime 3 installer uses a Temp folder in your boot drive for storing files needed during installation. Under Windows 95, this temp directory is located in the path "C:\Windows\Temp." Under Windows NT 4, this temp directory is located in the path "C:\Temp." This Temp directory may contain files from previous installations, that may interfere with the installation of QuickTime 3 (or other applications).

    1) Locate the Temp folder using the paths defined for your operating system and rename the folder to "OldTemp" or similar name.

    2) Create a new folder in its place with the name "Temp" (carefully using the same case and leaving out spaces or other characters).

    Note: The next troubleshooting step involves restarting the computer in Windows "Safe Mode." This is similar to starting up the Mac OS with "Extensions Off."

    3) To startup the computer in safe mode, hold down the Shift key before and during the Windows 95 splash screen. Safe Mode can be recognized by the words "Safe Mode" appearing in all four corners of the screen. You may notice a different resolution, or loss of colors. This is normal.

    NOTE: If you are using Windows NT 4, select the "Windows NT 4 VGA Mode" option at the boot manager.

    4) Launch the QuickTime 3 .EXE installer.

    5) Advance the installer until you get to the "Full Install" window. This window includes "Minimum" and "Custom" options.

    6) Press CTRL+ESC to display the "Start" menu.

    7) Use the "Start" menu to navigate to Programs: Windows Explorer (or Win NT Explorer).

    8) Using the Windows Explorer, verify that the following files are located in C:\Windows\Temp
    (or C:\Temp under Windows NT 4):

    NOTE: The file names shown below include extensions, viewed by unchecking the option for "hide file extensions for known file types" option. This can be found in the Windows Explorer: View: Options dialog box.

    - "_istmp0.dir" = installer shield folder
    - "_ins0432._mp"
    - "_inst32i.ex_"
    - "_inz0432._mp"
    - "_isdel.exe"
    - "_setup.dll" = optional for Win NT 4 installation
    - "_setup.lib"
    - "_wutl95.dll" = optional for Win NT 4 installation
    - "data.z" = main QuickTime 3 data file
    - "QTtext.dll" = optional for Win NT 4 installation
    - "readme.wri"
    - "setup.bmp"
    - "setup.exe"
    - "setup.ini"
    - "setup.ins" = optional for Windows 95 installation
    - "welcome.bmp"

    9) Locate and move any missing files into C:\Windows\Temp or (C:\Temp for Windows NT 4) directory using the Windows Explorer.

    10) Close the Windows Explorer and continue with the installation.

    If the installation continues to fail, it is possible that there is a software issue preventing QuickTime 3 from being installed, such as a software conflict or file association issue within the Windows Registry.

    For more information on troubleshooting software, please refer to your operating system documentation.
