Everything was fine, until Windows Update.
After login Windows told me to wait while updating my user account.
Now Lightburn is stuck to the splash screen.

I see this : Lightburn doesn't open (LightBurn 1.7.x -- After Windows Update)
I have try :

  • to reinstall the Visaul C++ redistributable without success
  • to reinstall lightburn without success
  • my material library is on a network, I try to delete pref.ini without success

I got this crash log :
Crash Log Stack Trace for LightBurn v1.7.06:

Try on windows》search %temp% and %temps% delete everything which can be deleted.
some files can’t be deleted it’s normal.

Found a lot of files under %temp% → delete all authorized files
Found nothing under %temps%

I didn’t believe it, but IT’S WORKS.
LightBurn can be opened now.

Thanks a lot.

With pleasure too.
It’s not just an helping hand.
You save my LightBurn license.
I’m a software developer and I can’t imagine that a software can be repair by just deleting some tmp files.
You are beyond an engineer, you are like a demi-god :wink:
