From poking around on the CnCnet forums, it seems like running the launcher as an administrator should fix the problem. Only, this isn't enabled by default by Origin (as far as I can tell) and Origin itself makes it really difficult to open the launcher for the game without using Origin directly.
I've seemed to have found an easy solution for users using Ultimate Edition. Try patching your Launcher for Ra2: Go to http://bibber.eu/downloads/cnc-ultimate-collection-launchers/ download and run the executable file enclosed. You hopefully shouldn't encounter the anti-piracy measures when you boot up Red Alert 2 after patching your installer this way.
Hope it helps.
