Diamond Scheduler 8 does not exhibit this problem. This issue occurs with Diamond Scheduler 7 only.

The error we hear about occasionally is a dialog box that says, “Sorry, an error has occurred. The application could not be installed because the installer file is damaged. Try obtaining a new installer file from the application author.”

In fact, the installer file is not damaged. There is likely a conflict of programs.

Fix Number 3

Diamond Scheduler uses Adobe AIR to allow cross-platform development. You should have the AIR plugin installed on your computer for Diamond Scheduler to work properly. Like Adobe Flash, AIR is often installed on users’ computers, but yours may not have it pre-installed.

If you have the problem mentioned above, we suggest the following to overcome the difficulties.

1. First uninstall Diamond Scheduler if it is already installed (Control Panel > Uninstall on Windows and Application folder on Mac).
2. Make sure the application folder does not exist (for Windows, it is most likely located at c:\Program Files\Diamond Scheduler 7 or c:\Program Files (x86)\Diamond Scheduler 7 and Applications folder on a Mac). If the Diamond Scheduler folder still exists after uninstalling the program, delete it.
3. Empty the Recycle Bin (Windows) or Trash (Mac).
4. Make sure your computer’s system clock is correct. Correct the date and time if it not current.
5. Install the latest version of Adobe AIR (download from http://get.adobe.com/air).
6. Try installing Diamond Scheduler again.
