Hi, like the title says neither the main program, ebook editor or viewer will start for me anymore after several years of using this program.
- It won't start in safe mode
- It briefly appears in task manager but then goes away
- I've tried reinstalling it, removing the configuration files in %appdata% and reinstalling it.
- I use windows defender with no other antiviruses apart from malwarebytes free
- It won't run with admin rights
- I downloaded it twice and it results in the same problem
here's a debug log:
Code:
C:\Users\gonkzonk>calibre-debug -g
calibre 5.5 embedded-python: True is64bit: False

Not controlling automatic hidpi scaling
Warning: QT_DEVICE_PIXEL_RATIO is deprecated. Instead use:
QT_AUTO_SCREEN_SCALE_FACTOR to enable platform plugin controlled per-screen factors.
QT_SCREEN_SCALE_FACTORS to set per-screen DPI.
QT_SCALE_FACTOR to set the application global scale factor.
I tried some solutions found in other threads but none of them helped. I don't know what else to do to fix this.

thanks
