Hi Michael,
Thank you for contacting Infragistics Developer Support.
I am currently setting up a virtual machine with your environment in order to test this. Meanwhile please answer these questions:
What exactly do you mean by ”not recognized the objects”? Does it not load? Does it throw an error? What error is thrown? Or is it just nothing happening?
When upgrading to Windows 7, have you changed anything else, other than the OS?
Can you record or replay test against the samples that come with TestAdvantage?
I am looking forward to your reply.
