Running Win7 64. I crashed Inventor 2012 yesterday. I clicked Send on the CER and got an Internet Explorer window with a link to a patch - inventor_2012_sp1_x64.msp.
I downloaded the patch and attempted to install it this morning, but consistently get an error message:"Another installation is in progress. You must complete that installation before continuing this one." (see attached).
According to task manager, nothing else is running. I've restarted the pc - no luck. There aren't any windows waiting for responses hiding behind these windows.
