Why does the user receive the following error message when trying to run the CEsetup?
Workbench was installed on the machine prior to running the CE setup.
Exception occurred while initializing the installation:
System.IO.FileNotFoundException: File or assembly name Ansys, or one of its
dependencies, was not found.
After the user clicked okay, it uninstalled itself.
In this particular case, it turned out to be a bad IIS installation.
Reinstalling IIS should resolve the problem.
