Visual Studio 2012 C++ Windows 32

Question

I had to switch to a new computer (64-bit, of course). I installed Visual Studio 2012 as before and opened my projects. I have code which is compiled for 64-bit and for 32-bit windows in two different projects, setting some constants and #ifdef statements. The first is x64 and the second ARM. However, Windows 7 32-bit claims that the second one is not a proper Win32 application and refused to start the EXE (users told me that and I confirmed in an XP installation in a virtual box). However, everything workd fine on my previous computer (a 64-bit computer too) and I did not change a word in the settings or the code.

Now I know that this is difficult to answer without details. But maybe someone has an idea what could go wrong.

I try to provide some details below:

The project type is set to "Release" and "Win32". It says "ARM" in the box below the menu bar.

Thanks for any help.

Answer 1

The fact is that Windows XP is no longer supported by default, as Hans Passant pointed out. I gave up supporting this version. The program runs on Windows 7 32-bit just fine.
