We recently received some help from a customer on this issue when installing Inventor 2014 from the Product Design Suite.
Error 1920. Service 'Autodesk Simulation Moldflow MITSI 2014 Job Manager' (mitsijm2014) failed to start. Verify that you have sufficient privileges to start system services.
To resolve this issue, just rename msvcr100.dll to msvcr100.bak. This file is located here:
NOTE: This could apply to any Suite that has Inventor in it.
I would like to thank the Williams-Sonoma IT team for sharing this solution with the community.
