My company just purchased me a new PC. It's Windows 7, 64-bit. My old PC was Windows XP and I had Compaq Visual Fortran 6.6 with F90SQL and MS Visual Studio 2005. I installed MS VS 2012 but cannot install Compaq VS 6.6. My applications that I build will be used by fellow employees. What product do I purchase so that my Fortran and F90SQL routines work?
