Tutorial using CI 8.0.0

Hi guys, i'm looking for a bit of help here.
I'm making a repack of crysis 2 with (obviously) yener90's custom installer, and i'm stuck at the "SaveGameFolder" section in the Setup.ini.
Crysis 2's saves are located in the Saved Games folders:
C:\Users\Username\Saved Games\Crysis2
I'm having trouble with the "Username" part because i know i must use the costant {username}, but when i uninstall the game the uninstaller won't recognize it. Is there a way to implement this costant in the InstallerScript.iss (or any other way to make the costant work) ?

EDIT: Solved. I put "Username" instead of "username". Damn lower case.

Is there a way to execute a .bat file after the installation? I tried putting it in the [launcherSettings] section of Setup.ini file but it didn't work.
