I downloaded it from http://www.cnc-comm.com/community/index.php?action=downloads;sa=view;down=21
I also installed Red Alert using the Red Alert Setup Manager v0.98 and it can run without the CD.
RA+ 3.03 is installed in the suggested directory, C:\Westwood\RA+
The error I'm getting says:
Red Alert: ra95.dat - No Disc
There is no disk in the drive. Please insert a disk into drive D:.
