CDB Debugger crashes on startup

  • I'm having a problem where CDB will crash as soon as I try to debug my application. This is not just project-specific: it happened on one of my large-ish projects as well as a test console application I made. Applications run normally if not being debugged.

    The debug log is as follows. It doesn't seem to list the exit code of the application.

    The application output just says:

    Debugging starts
    Debugging has finished

    I have reinstalled Qt Creator and repaired the Windows SDK but to no effect. I was able to debug applications previously but hadn't changed anything (to my knowledge) to cause the debugger to fail.

  • Can you run a small example that comes with Qt and confirm that even there the debugger is crashing?

    Go to C:\Program Files (x86)\Windows Kits\8.0\Debuggers\x64
    Can you find any thing there. Have you installed the debugging tools for windows? Have you installed the correct version(32 bit) of it?

  • I ran examples/uitools and the same thing happened. I've checked the folders and have CDB for both x86 and x64.
