i can play reforced but not versus or the dlcs

New to this game. What do I install on my PC? I have the reforced and the expansions also the versus. The versus seems to have 44gb and the others a lot less. I just want to play the campaigns and skirmishes, which one do I install? Thanks!

Could it be that the AI ​​has a bug with the trolls? No matter how long you play and even at the hardest level, the trolls never completely expand their camp or bring the best units/titans. I haven't played a game where the trolls were really a threat. Even against other AIs, they are always by far the worst...
