Revit 2014 crash at startup

You have your Autodesk products i.e. Revit 2013, working properly except Revit 2014, basically when starting Revit 2014, it just crashes. 

To figure out the problem, we used Procmon to find the problematic file "PackageContents.xml" located in the folder "C:\ProgramData\Autodesk\ApplicationPlugins\sofistik bimtools.bundle". It was not granted with proper access for the logged in user account.

Procmon Workflow:  Revit-2014-denied

We added the corresponding USER account with Full permission to the file which solved the issue.

Thank you to Hashim Mundol for helping us on the process.
