This article is the AppleShare 4.2 to 4.2.1 Updater Read Me file.
DISCUSSION
Apple recommends that all customers using AppleShare 4.2 or AppleShare 4.2 v1.0.2 upgrade to AppleShare 4.2.1, which supersedes the previous releases.
There are two ways for customers to do this. First, they can call (800) 293-6617 ext 759 and order an upgrade kit for the cost of shipping and handling ($6.95).
The other method of upgrading is to use the AppleShare 4.2->4.2.1 Updater.
Note:
The AppleShare 4.2 to 4.2.1 Updater will not modify AppleShare 4.2 v1.0.2. Those customers will need to use their original AppleShare 4.2 CD-ROM to drag the old version of the File Server Extension to the extensions folder. An alternative to the drag install is to run the AppleShare installer again and replace the AppleShare 4.2 v1.0.2 application with the older AppleShare 4.2 when prompted.
Installation Instructions
On a system with AppleShare 4.2 already installed, complete the following steps to upgrade to AppleShare 4.2.1.
1) Double Click on the patching application
2) Click on the patch button.
3) Four components will be patched. You will be prompted to locate each of the following in your system folder.
