Can't run TestStand 4.1.1

[Skeptical]

I recently installed TestStand on my computer. Version 4.0.2 seems to run fine. However, I updated it to 4.1.1 and whenever I try to run it, I get the following Sequence Editor error:

Creating an instance of the COM component with CLSID {B2794EF6-C0B6-11D0-939C-0020AF68E893} from the IClassFactory failed due to the following error: 80004005

I tried repairing the install but that hasn't helped.

Thanks.

There's usually a message that appears before that one and tells you to use the version selector to change the active TestStand engine. Have you done that after using 4.0.2?

There was no message appearing before it. However, before I got your response, I thought I would try uninstalling and reinstalling TestStand 4.1.1. Since, then it works fine.

More than likely, your solution would have worked.

Thanks for the response.
