Hallo Jeff,
thank you for your help.
I am using InstallShield 5.5 from 1999 which does not support msms.
I tried to find an answer by myself yesterday and came to a similar solution. I opened a sample project, created a msi and installed it on my own system.
The problem was: It did not overwrite my cvirte.dll.
A second try after deleting my cvirte.dll succeded.
The file has been updated from version 7.0.0.393 to 7.0.0.394.
My InstallShield distribution kit, installed on a german Windows98, did work fine with bold fonts, which had been a problem with the former cvirte.dll.
It is comforting to know, that no other patches or updates are necessary yet.
Thank You!
Kai
