Hello Guys,

I have a problem, that I can't upgrade a file for a project from Revit 2015 to 2017 because of some corrupted groups in the original file, I tried to audit the file and fix it, then to upgrade it, but it's not working, can you help me please, you will find the file in 2015 version attached.

@Anonymoushello, try to clear all the warnings first in revit 2015 before upgrading to Revit 2017. Or to delete all errors when opening in Revit 2017. thanks

 Hello ennujozlagam, I have tried both solutions without any results, I cleared the warnings and upgraded the file, after I it asked me to delete the courrpted elements, I click on OK, then it gave me an unrecoverable error has occured, then it shutdown.
