Hey there, I've been able to use Qt Creator for quite a while now. Today I've tried to open Qt Creator a second time (2 at once) which resulted in a Bluescreen. After restarting I'm not able to start Qt Creator anymore. Tested with reinstalling (online and offline installer) with Qt 5.13.0 and Qt Creator 4.9.1. Starting as admin does work, but is not the workaround I'm after. Starting with "qtcreator.exe -noload all -load Core" opens Qt Creator with a very stripped-down version.

I hope this can be resolved soon. Thank you in advance!

@chrizbee Can you try to start Creator with the parameter -tcs (temporary clean settings)? From your description, it sounds like the settings are corrupted and Creator therefore does not start.

@aha_1980 said in Qt Creator 4.9.1 does not start on Windows 10:

Anyway, if it works in a fresh user account I'd probably rename my account, create a new one and copy over all the things I need. It's a bit of work, but still faster than reinstalling the whole system.

I actually ended up reinstalling the whole system. Still, this should not happen...

@chrizbee I have three or more more instances of Creator open daily, so I'm pretty sure you had really bad luck...

This should never happen again.
Qt has to stay free or it will die.
