In the past days I tried two different versions of the VS community with update 3 (one of it the express version). I downloaded them both from microsoft and installed them as usual. Both times everything worked perfectly and the launcher was still installed, but the problem is that the engine does not recognize my VS then. Could that be because I used the German version? Anyway, this time the launcher was still there at least.
I also asked in the VB forums if someone else had this problem, but they didn’t. They also advised me to try the download from MS, but no external VS is being recognized by the editor…
I hope that helps
