Changing the installation folder

I've just installed TS4, but was forced to change the installation folder to E:// instead of C, because I don't have enough space on my C drive.  I was wondering what this does to the game and future updates, do I just have to make sure it's all going to E drive, or is there a certain process when installing future expansion packs and fixes?

Update: Can't even change the installation folder anyway, it will only install to C drive  looks like I'm not playing TS4

Yeah, unfortunately it can only be installed in the C drive. How about uninstalling/deleting some files on your C?

I would, but unfortunately it's just a 55GB SSD for my OS, and a few more basic programs.  My E drive is my 1TB for games :c

You can transfer the game to your E drive by simply moving the folders there, you'll just have to do a bit of registry editing.

There's a topic on it here.
