1)Install Starcraft II to its Recommended Directory (or any logical custom folder you wish it will be detected)
2)make sure you find and download the latest cache files for sc2, and update the game to its latest pacth version by simple running it once.
3)then downlowd THIS Tool and install it to its RECOMENDED LOCATION
default path should be: C:\Program Files (maybe x86)\StarCraft II Beta\SC2ALLin1
IF the installation is not installing to the right subfoder and deletes your game directory is because you made once the stupidity of installing it there and now it remembers it! so go and extract the setup manually and place the folder there by your self!
(also wrong shortcuts may accrue from this mistake of yours! go and delete all non game files in its directory or do a clean reinstall of the game!)
OR simple re-download the latest setup that will prevent your mistake to happen again!
4)* Your System MAY require the .NET 3.5 SP1 download to be installed (Windows 7 dont) without this will not start and crash!
also in some stupid windows installations the “Verdana” font is missing!!! Make sure you have that also installed (google it) otherwise the tool again will crash on startup!
