I believe it's the ultimate version that i have. it was a bundle i bought on steam that contained red alert 3, red alert 3 uprising,C&C 3 tiberium wars, C&C 3 kanes wrath, and C&C 4 tiberium twilight.
The error i get when i try launching any of the C&C games is CA public key patching routine failed. I have read that it is one of the common problems and that i should try a different compatibility for it. I have tried different ones and none seem to be working it just gives me the same error message.
I am using windows 10
