Hi All

Hoping somebody can help me...

I recently swapped out my old Windows 10 laptop for another and tried to reinstall Calibre however after installation I can't actually launch it...

I have tried installing Calibre 64 & 32 bit, even tried launching the portable Calibre and all refuse to launch at all. (I also don't see a new process in Task Manager either). Compatibility mode and running as Admin doesn't help either.

However, if I boot into safe mode, I can launch without issues with any of the versions (64/32 bit or portable). I know this means there is something on my machine causing issues, but I have no idea what it could be. I disabled (then uninstalled to be sure) my antivirus and have nothing abnormal in my startup services / applications.

I have ran the calibre-debug command, but I don't get much back. I'll paste what I get at the end of the message.

Any suggestions on how I can narrow down the cause?

C:\Program Files (x86)\Calibre2>calibre-debug -g
