I installed RA1 on my XP comp a while ago no problem, using the usual "compatibility mode" shortcuts and the patch. But when I tried the same thing recently to install Counterstrike, it coughed. "Compatibility mode" gets the setup program past objecting that I'm running "Windows 5.1" ( ), but now it's complaining that it's "Unable to load nessicary files. Please run Setup.exe from the CD-Rom disk." Any ideas?
