I used SVN then exported to a new folder due to it auto updates. I'm sure there's an easier way.
Download Microsoft .NET framework 4. That should do the trick
What? I used TortoiseSVN to get ProfessionBuddy then right-click, export to create a non-SVN version since the bot base automatically updates itself.
You need to install the .net 4 full version. Found here Download: Microsoft .NET Framework 4 (Web Installer) - Microsoft Download Center - Download Details
