I'm using Windows InstallScript MSI Project.

When compiling inside ClearCase, every then and again I get Fatal Error 0:

Media table successfully built
ISDEV : fatal error 0:
Product Configuration 1\Release 1 - 1 error(s), 1 warning(s)

It happens on IS9, ISX, and IS11.
Often reboot resolves the problem.

When I build the release outside ClearCase (version control), it works fine.

Does anyone know what can be the root cause for this?

I don't think I have any custom actions, nor RTF files ...

Thanks in advance,
