I have a huge problem with Inventor 2015 on a win8.1 64 machine
Inventor always stops responding after a working break over about 1 hour.
With a deeper look inside i find out that Inventor.exe process is waiting for a rpcss.dll svchost.exe
I saw this behavior sometimes in WIN 7 64 only with a short not responding break. Most in drawing environment
For win 7 64 there is a hotfix KB 2637692 for this problem. Does anybody have the same issues?
