Question by Denis N. · Apr 05, 2013 at 10:15 AM ·

DllGetClassObject... 1 is not a valid Win32 application.

Hi all,

finally I got the possibility to get dT running on a Terminal Server, by publishing the Agent-Tool itself as TerminalServer-application.

Now I was able to configure an Agent, but I'm getting an error. Following is the Log:

2013-04-05 09:59:33 severe  [native] DllGetClassObject: %1 is not a valid Win32 application.

Anyone a suggestion about this issue?

Thanks in advance!

Denis

Thanks Andreas, I'll do so. And no, it is a 32bit application.

That is interesting. First of all I would open a support ticket.
My gut feeling about this is that DllGetClassObject tries to load our .NET Agent library (dtagentcore.dll). It fails though as it thinks it is not a valid library. Is it possible that your .NET application is a 64bit application? But we try to actually load the 32bit agent dll?
