Cons: Requires .Net 4
Other Thoughts: What is the point of this launcher? You can't launch the launcher until you install .Net 4.
Most computers don't have that installed, & even if they do, Windows 7 comes with just 3.5 by default.
Forget using this portably.
Needs .Net 4.
If your using on the PC, this may not be that bad, but that defeats the purpose of using a launcher portably.
