I have installed on my machine ONLY Autodesk Inventor 2012 sp2+update1.
When I start Task Scheduler, I view the message:
"The the latest Autodesk Inventor version used on this machine not correspond to this version of Task Scheduler."
Thank you very much.
Did you have any other version of inventor installed? Maybe there's some files left. Check in add/remove programs for any left inv installs.
Cleaning registry and user files also helps.
