Okay... I know this must have been answered 1000's of times over since EA dropped support for TS2, but I recently decided to return for some nostalgic gameplay.
How do you install TS2 without support from EA? EA recognizes I own the rights to the game because it's available for me to download from Origin, but when I go to install TS2 Store Edition [tried downloading the install file into a

\folder] it tells me, "This product requires an installed copy of TS2. Please install TS2 before installing this product." What???
If I can get past this hurdle, I'll face another one: I have all the expansion packs and stuff packs... How can I install them when the original CD's required online verification that is no longer supported?

I'll worry about expanded content later.
You shouldn't need online verification with the disks. What message are you getting from trying to install the disks?
It will offer a chance to register them but you don't have to register the games; choose No.
