V25.0.50  does not crash when opening files.
V25.0.52  ,53  ,54  all crash when opening files. 


This might be a bad install of " msvcp140.dll "  in the system32 folder.


Replacing this file with a known working one can fix this issue.


*** The file " msvcp140.dll " seems to get locked out by some MSI Center software, specifically the CC_Engine_x64.exe process.  Making sure this process is not running before installing GibbsCAM may prevent the issue in the first place.


How to crash dump.


I have attached the reg files to enable crash dumps.

If you're an admin, just double click on the "enable_local_gibbscam_crashdumps.reg". It simply turns on crash dumps for GibbsCAM.
Run GibbsCAM and get it to crash
Navigate to: %userprofile%\AppData\Local\CrashDumps
You'll see at least one Virtual####.dmp file. Zip that up and send it to me.
Now double click on disable_local_gibbscam_crashdumps.reg
No more crash dumps will be saved.


WinDBG  can be used to analyse the dump file.
