Hi,

I've made a very simple 32 bit application on 32 bit OS (Win XP) but I cannot execute it on 64 bit OS (Win 2008 R2).

It simply crash when running it with message :
"The application was unable to start correctly (0xc000000f)"

I've read lot of posts but I cannot find my answer.
I do not need to have pure 64bit application and I do not want to have 2 different/separeted executables.
I just want my 32bit runs on 64bit...

Any idea ? Thanks.
Tom

There isn't a problem to start 32bit code on 64bit OS. Probably you violate any privileged rules or a library is missing. Google reveals some more ideas.

Hello, Make a simple test. Build a empty form in your windows Xp.
Then move the exe to Windows 7/64Bits, and run it.
