QProcess: can you call a 64 bit executable from within 32 bit Qt App on Windows 7?

Thanks for your answers in advance.

I do not see why not.
Have you tried and it did not work?

Yes, you can. By default though Windows will redirect calls from 32-bit applications to any 64-bit system applications to the respective 32-bit counterpart. To avoid it you should disable the file system redirection as explained here:
https://msdn.microsoft.com/en-us/library/windows/desktop/aa365743(v=vs.85).aspx
Applications that are NOT in the system folders (Program Files, Windows, System32 ect..) should not be affected.

I am not sure though if Qt includes this functionality in its classes, or if you have to do this manually by linking with the kernel32 library and calling the appropriate function.
