The At Ease 4.0.1 Updater attempts to patch three files:
* At Ease - In the System Folder of At Ease Workstations
* At Ease Startup - In the Extensions folder of At Ease Workstations
* At Ease Administration - An application located in the Network
Administrator Toolkit folder of computers with the administration
software installed.
If a user performed a custom installation of the At Ease Administration software without installing the workstation software (which is a supported configuration), the At Ease and At Ease Startup files will not be present in the system.
The first file the updater needs to patch is At Ease. If the user does not have this file installed and tries to skip it, the updater will cancel the update.
This issue has been reported to Apple engineering, however, there is no known date a fix will be available.
Workaround
----------
Perform one of the following:
* Install the workstation software on the administration computer before running the update,
or
* Copy the At Ease and At Ease Startup files from a workstation to a floppy disk. Insert the floppy disk into the administration computer before running the update. When the updater asks you to locate the file "At Ease" point it at the file located on the floppy disk. It will then let you update the At Ease Administration program on the hard disk of the Administrator computer.
