QtCreator crashed and now will not start due to segfault
-
Yes, Qt-Creator just won't open at all, even after I re-install the entire thing.

there is
C:\Users\username\AppData\Local\QtProject
C:\Users\username\AppData\Roaming\QtProject
which can be left over even if reinstall.It should be pretty safe to delete, but Creator will forget anything then.

Do you have sessions enabled ?

to see if anything is written ?also when starting in cmd.

I get a segmentation fault when I run it from the cmdline both without and with arguments.

There's, oohh, a 1% chance that if you try running Qt Creator from within a debugger like Visual Studio (if you have that...), when it faults you'll get enough information from the stack trace to hazard a guess as to where it's going wrong... -

I just debugged it and got this: Exception thrown at 0x670E5DA7 (Qt5Core.dll) in qtcreator.exe: 0xC0000005: Access violation reading location 0x7E5B8721.

Is it possible that the wrong Qt DLLs are loaded? Have you changed the PATH environment variable, for example?

No, that's not what I meant! I meant, have you done before? Or have you installed some program that did?

Take a look at qt.conf in the creator/bin directory. If it's corrupted then plugins wont load.

It's not corrupted because it's a clean install

@TMcSquared
Best guess is that it gets wrong QtDLLs maybe via
path. -

My PATH variable has zero Qt paths in it. even after a clean install.

Hi,
Then it sounds like a graphic driver issue then. Are you sure there wasn't any modification in that regard on your machine ?

You could check whether Windows Update snuck in and did anything since it last worked... :) -

That's completely possible, thanks for your guy's help!
@SGaist I have no idea, it quit working while I was logged in.
