I am trying to install the new 9.03 release on Windows 10
Under Help I clicked Check for Updates
it found version 9.03 and asked if I wanted to download it
I clicked Yes and it downloaded the new file.
I closed the current instance of LighBurn
When it finished downloading I double clicked the LightBurn-v0.9.03.exe file
it stated the install process then about 30 seconds into the install I got this message
I clicked the Retry button and it did retry, but had the same problem again.
Are you sure your malware protection isn’t blocking a modification/deletion of the LB file? Mine can be aggravating that way and I have to go into the software to find the log to see what files are being blocked and set an exception for them.
@Grumpy_Old_Man is right. Windows doesn’t always release files properly when an application closes. This kind of crap used to happen to me all of the time on windows. Rebooting is the simplest way to resolve it.
