C Compillers for 64 bit Windows 7

Hi !
I have intel core i5-650 processor (64 bit), 6 GB RAM and 64 bit Windows 7 ultimate. I am unable to install Borland Turbo C++. Also I couldnot find any 64 Bit C compiller which could be installed in my PC. Kindly suggest some compiller for my PC or else should I instally a 32 Bit Windows 7 ultimate ?

Have you tried it in XP Mode in Virtual PC ? Both are free from MS and will run on Windows 7 Professional and Ultimate. Also, try Compatibility Mode. Just right-click the program in the Start Menu > select Properties > Compatibilty > select run this program in compatibility mode for which every version of Windows that you know it worked with. You may also have to check the box in that windows that says Run This Program As Administrator if it worked on XP or earlier Windows versions.
