Error Message - Specified cast is not valid

I use the feature “Stop ConfigMgr Client Activities” and after the confirmation i get this error:
image
RCT version 4.1.2002.3003

The function works, the ccmexec service was stopped but i think the message should not appear.
I tried with version 4.1.2001.3101 and got the same error message.

Thanks for reporting the issue. I’ve added it to the backlog and we’ll post here when it’s fixed.
