A serious error has occured. The action will be canceled - Upgrade 2017

[Anonymous]

Helo everybody!

I am an Architect and the company where i work, we a update our package Autodesk to 2017. But I try open a file in Revit and appear a message "A serious error has occured. The action will be canceled".

I came back to open in 2016 and used Audit, removed Worksets, used Purge, but nothing resolved the problem.

Help me please. My team needs to work in this archive.

Thank you very much

All of the Service Packs and Updates Releases, etc. can make a HUGE difference. Make sure you have every update available installed. If that does not work, I would try an uninstall, then reinstall.
