I have a code package of about 10,000 lines of Fortran, developed over the past 30 years. The GUI for the package is currently an F90 QuickWin application, maintained on a WinXP system using Digital Fortran 6.0. I bought a Win7 computer (HP, with AMD Turion processor) in November, 2008, and the program continues to work perfectly on that system. However users are now reporting that the program loses focus and fails to recognize mouse clicks. I suspect that this is due to Microsoft making incompatible changes in Windows calls, and I will have to update my Fortran compiler to fix the problem. [I learned about this change from the Release Notes of Intel 9.0]
I purchased the Intel Visual Fortran Compiler Version 9.0 some years ago, but was unable to install it at that time because I didn't have an appropriate Visual Studio or C++. I am now attempting to install under Win7 on my HP. Whatever I try seems to require prerequisites that I don't have. I sometimes get the message that the processor in incompatible with the loader, and sometimes I am told the installation was successful but I can't find any execute. I have in the meantime installed Visual Studios 2008 and 2010 Express, but neither includes the Fortran compiler.
Can someone tell me exactly what prerequsites I need, and what should be to procedure to instal IF 9.0 - or is that so obsolete it is impossible?
