I’ve bought ME2 (from Direct2Drive) and now that the release date came, I wanted to install it.

After downloading the 9 Gb pack I extracted the rar file and ran setup.exe:
Language: English, Ok, Yes I want to install, Next, I Accept the EULA, I Agree… Installation canceled? Uhmp, silly me, I must have accidentally clicked on “cancel"…
Okay, Finish, lets start over. Setup.exe, Ok, Next, I Accept, Installation canceled. What the hell?!

After spending an hour tracking down the problem on forums, it seems that the installer fails on Win7 x64 systems. Here we have a AAA game with tens of millions of dollars spent on the development (and twice as much on marketing) and the fucking installer doesn’t work… Well done! Yeah, I know, windows 7 is a rare, exotic operating system, I can’t expect the developers to test the installer on it… Oh wait… Win7 is the best selling OS in history.
Now I’m trying a manual install method, made for MassEffect 1, where the user copies stuff manually to the proper directories.

I wonder if there is an achievement for being able to install the game…

EDIT: I take everything back.
It was DirectoryOpus. Its zip extraction screwed up a few files, one of the exe files was copied into in several ini and rar files for some reason… o_O
7zip was able to perform the requested operation flawlessly, so its installing now! Fingers crossed.

EDIT2: It runs without a hitch.
