Delphi-XE5, ODAC 9.1.4
Are there known problems to connect to oracle database when the application is installed on Windows 7 embedded?
When the app tries to connect this errormessage occurs:

The funny thing is that when we set the application to compatibility mode WinXPSP3 then all works fine. But that should not be the solution.
Any idea?
Thanks for help and kind regards,
Robert
