Can't run 64bit QMainWindow default project -Windows 10

ChiefGeo

Hello,

I am having difficulty running a stock QMainWindow project through Qt Creator. I get the message:
21:35:22: Starting C:\Programming_IDES\Qt_projects\build-TodoApp-Kit2_64bit-Debug\debug\TodoApp.exe ...
21:35:22: The program has unexpectedly finished.
21:35:22: The process was ended forcefully.
21:35:22: C:\Programming_IDES\Qt_projects\build-TodoApp-Kit2_64bit-Debug\debug\TodoApp.exe crashed.

When I use a 32 bit kit everything works fine. Switching to a 64 bit kit causes this issue. I am able to run a console application with the 64bit kit.!

Trying to run in debug mode does not help. The debugger exits and the app never appears. I'm not sure what could be the issue. Thanks in advance.

@ChiefGeo Try to run the exe outside Qt Creator.
Simpliest way: copy the exe to Qt bin dir and double click to run it.
Sometimes you'll get infomation about what problems cause the crash.

@ChiefGeo Do you have anti virus software running?

ChiefGeo

@jsulm The only antivirus protection I have on is under Windows security. I turned that off, relaunched the app and it fails the exact same way still.

Any word on this?

@Bonnie Thanks for the advice. After doing what you instructed I found that my Qt5Gui.dll was corrupted (maybe a few others also). Reinstalling Qt from scratch has fixed the issue. Thanks!
