APPCRASH Fault Module Name: XojoGUIFramework32.dll

I have a user of a program I wrote with the Xojo 2015R2.2 , who is getting a crash as soon as he opens the software on his Windows 7 computer.

I have tested, and not been able to replicate this issue. I have no idea where to even start as far as troubleshooting this. Any input would be much appreciated.

Problem signature:
Problem Event Name: APPCRASH

The error indicates a “Floating-point division by zero”. Googling brings up all sorts of things like it could be 64-bit/32-bit compatibility issue, or the application is set to start in full screen mode (and is not capable of doing that), etc. Difficult.

Have the user turn on mini dumps
(sadly I cannot find anything on MS forums etc)

Thanks, I will look into these things. From what I am readying though, the mini dumps are only created if there is a BSOD (blue screen of death)?
