So many issues....playing command and conquer red alert 2 the game crashes second or third mission in. in yuris revenge, i cant even click on the skirmish or load saved game option. in red alert 3 and command and conquer 3 campaign i cant even click on some of the buildings in the building tab, or even some kinds of units. even though the building is unlocked.
Are you talking about The First Decade, or about The Ultimate Collection? C&C3 and Red Alert 3 are not part of the First Decade pack.
In fact, this sound a lot like an issue that has been popping up a lot recently, which seems to be caused by the Origin game launchers. They appear to leave an invisible window on top of your game that prevents you from clicking in certain areas. From what I've seen, installing Bibber's fixed game launchers generally seems to solve the issue.
For the rest... Command & Conquer 1, Red Alert 1 and Tiberian Sun have all been upgraded with community-created unofficial patches that fix a lot of their bugs and compatibility problems. For Red Alert 2 there's a more general patch that solves a lot of its graphics problems. You can find them here:
