Because of a known issue between the interaction of the licensing software and the ASP.NET service in Microsoft Internet Information Services (IIS), a problem can occur when you uninstall System Architect XT.
To prevent this problem from occurring, follow the procedure below when you uninstall the application:
1 Inform users logged onto any applications being hosted on the same IIS server as System Architect XT that the server will be taken down when you uninstall the application.
2 From the IIS console, stop the IIS service.
3 Uninstall System Architect XT. Navigate to the Add or Remove Programs utility from the Control Windows Panel. When the process completes, delete these folders:
C:\Program Files\UNICOM Systems\System Architect Suite
If you receive a “file in use” message when attempting to delete these directories, run the IISReset utility and try deleting them again.
4 From the IIS console, restart the IIS service.
While restarting the service, an error might occur. You can ignore that error because other applications are not affected, and the ASP.NET service will be restarted when the IIS service is started.
