I have uploaded a .rar containing four batch files. Two of them move the files to Update2. MoveC and MoveD. So if you have C as your main drive, use it. If you have D, use it.
The two other files are MoveBackC, and MoveBackD. They do the same things, except move back. The only files that are necessary to move are the .dlls, the HSUpdate.env, HSUpdate.exe, and the update folder (I am not sure about this one).
So follow his directions, except when you are running the program, use MoveC/D first, then MoveBackC/D instead of running it again.
If your main drive isn't C or D, Just change all the "D:\'s to "X:\. X being your main drive, of course. If you can't do that, just tell me the letter of your drive and I'll make one for you. An easy way to do this is to open the file in notepad, go to Edit, choose replace, search for "D:\ or "C:\ and change it to "X:\.
