Hi,
i've written a small application using c++, Qt and Visual Studio 2010. It's working on Windows XP (32bit) but it crashes on Windows 7 (64 bit) right after start-up. I see a "The program has stopped working..." error. Do I have to recompile the application for Windows 7? And is it possible to get more information why it crashes?
Thanks
In general you wouldn't have to recompile for windows 7, but it depends on your application which you haven't provided details of.
The easiest way to find out is either debug it in windows 7 or put more error handling in, so that it lets you know what has gone wrong, or where it has gone wrong
You might have to recompile for Windows 7/64bit. It might not even work after a recompile, since Windows 7 is not XP, and a program written for 32 bit might not work for 64. Often one don't have to recompile, but sometimes one have to, and some times a program which works on XP won't work on Windows 7.
I agree with what martiert said, also, if you are using some external elements, images. sound files, video files, etc ... be sure of the file location asd this was a problem for me when I was presenting my graduation project, I moved the whole solution from a directory to another and it crashed because it was reading a not found directory ... so be sure of the links of the images, videos, sounds etc ...
