As was said, please try to look around more.. I'm pointing these out in the hopes that no one else will ask this same question again.. at least for a week or so.

"Visual Studio 6 - Load the workspace. Set MQ2Main as active project. Hit Build MQ2Main.dll (F7). Now do Batch Build (under Build menu). Make sure everything in the batch build window that says "release" has a check by it. Click Build in the window. All should compile with no errors or warnings."
1. Double click MQ2Auth.exe
2. Double click macroquest2.dsw
3. Select Build -> Set Active Config and select MQ2main; hit ok
4. Select Build -> Build MQ2main.dll
5. Select Build -> Batch Build; push Build button.
6. Go into release folder and double click macroquest2.exe
It really doesn't get any easier then that.
Yes, you either need to buy VS6.0 or find someone to "borrow it". Whether online or irl.
