I'm trying to update our machines up to VDF19.0

Therfore I run the installationfile and everything seems to be OK.
But at the end of the installationprocess, the following message appears.
Click image for larger version. 

Name:	Error.jpg 
Views:	41

After clicking OK for multiple times, the helpfile appears and then the studio. Everxthing seems to bo OK.
Opening the orderentry-workspace rund perfect, but if I try to compile, the same error appears: Dataflex not installed.

I have tried several ways to install VDF19:
- setup from the local PC and not from the server
- setup started with administrator-rights
- PC started with a user, whose VDF19 was installed correct.

There's enough space on hard-disk
and the installed files seem to be complete.

So it semms to be a malfunction in the registry.

Any ideas

Thanks a lot for answers
