I can't run applications Compiled in C++ in my windows XP machine?

I have downloaded the Borland 5.5 C++ compiler only (no IDE) and I have succsefully compiled and linked the program.





But when I try to run the executable from the DOS prompt, I get a "this is not a valid windows 32 application, access denied".

Run all updates to windows and install the IDE for Borland.
