I have the complete collection, but can’t play as the Asian factions or Indian?

Normally there’s 2 icons in my desktop, one for Asian dynasties, which (when clicked) allows me to play both expansions. But for some reason I can’t find that ANYWHERE in my computer. There’s only a desktop icon for “Age of Empires 3 complete collection” which doesn’t allow me to play (or even show up in game at all) any of the expansion content I’ve paid for, long ago. If there’s a way around this without having to delete and re-download, that would be great as internet has been slower with this lockdown and I’m only on VDSL internet connection. Cheers
