Hello OliAH,
you're right! ODBC connections only show up in Machine Data Source and they also do in my ThinApp!
Maybe my ThinApp is working properly, but I still face problems with an .adp-Database. The Database is annoying me with the setup routine for MS Office 2010 starting up after logging on to the database. I have been able to prevent this in the past by putting an old mscomctl.ocx into the folder %SystemSystem% and de- and reregister the mscomctl.ocx on the master. But after changes on the master this behavour is back, even after de- and reregistering the Activex component mscomctl.ocx.
Think I'll have to open up a new post for this.
Thanks a lot!
