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.
