Hello all! Recently upgraded to 1.7 which was working fine - today Windows 11 did an update and Lightburn would no longer start. Tried rebooting, reinstalling both Lightburn and redistributable stuff with no luck.

Event viewer:
Faulting application name: LightBurn.exe, version: 0.0.0.0, time stamp: 0x671a49b1
Faulting module name: MSVCP140.dll, version: 14.13.26020.0, time stamp: 0x5a39fef7
Exception code: 0xc0000005
Fault offset: 0x000000000001b93c
Faulting process id: 0x0x21C8
Faulting application start time: 0x0x1DB32206C15B926
Faulting application path: C:\Program Files\LightBurn\LightBurn.exe
Faulting module path: C:\WINDOWS\SYSTEM32\MSVCP140.dll
Report Id: d669845c-5afc-4fc4-87ea-7e4f19d2c3a1

Downgraded to Lightburn 1.6 and all working again.

Any ideas?

Thanks
Andy

I’d suggest you try fully uninstalling LightBurn and any 14.x C++ redistributables. Then installing the latest LightBurn.

I’m having the same hang problem. Uninstall/reinstall of C++ and LB isn’t working.

It’s a 64-bit Windows 11 that just upgraded itself to 24H2.

I’m involuntarily offline until this problem is resolved.

Did you ever solve this? I am getting the same error now as well, and Lightburn crashes before a loading screen is even seen.

This was also after the latest Win 11 update.

Install/reinstall of C++ redistributable(s) did nothing, Uninstall/reinstall of LB also did nothing. Attempted a DiSM regresh/rebuild followed by an SFC /scannow, no corrupt system files. Please report back if you found a solution?

I’m encountering the exact same issue. Windows update - restart - Lightburn will no longer start.
