I've been building MQ and MQ2 without issues for about 5 months now. Today I got a new download of the zip, unzipped it into a new directory. Ran MQ2Auth. Opened the .dsw file ( when I double clicked on the .sln it told me the selected file is not a valid Visual Studio solutions file ). Set MQ2Main as the active project, built MQ2Main with F7, then did a batch build. Everything compiled without errors but I don't have a new MacroQuest2 exe.
What am I doing wrong?
Edit: Forgot to mention I'm using VStudio 6.
