I found it a problem on my old installation CD but I bought a new copy recently in a sale and it works perfectly.I miss C&C Generals - I've wasted so much time trying to get it to run on Windows 10 (and even 7, if I remember correctly). Is that still an issue with it?
8-bit Armies is done by some of the same developers.
You can also get a free version of Red Alert from cncnet.org which is truer to the original than openra, but maybe check out both versions and see which you prefer?
I believe there is a group of individuals which have modded all the C&C games so they worn on new OS's and got private servers up and running for multiplayer too. if you find it let me know as i was planning on installing it and forgot.
Does wither C&C Generals or Red Alert 3 work on Windows 10?
