It's just unimportant stuff in HKCU. I guess it's different from user to user.
Root: HKLM; SubKey: SOFTWARE\Wow6432Node\Blizzard Entertainment\StarCraft II Retail doesn't exists for me.

@Gatosky: If you decide to go without UA you can go that way that REV0 does with extra cab files for cache files.

Or include whole cache files folder into Setup.exe directly through [Files] section.

Whatch out for additional Flags in inno help file.
