Already Installed Error

Apr 9, 2012 at 10:41 AM

Hello. I'm using VS2010 Ultimate. Sometime ago late last year (around November time) I installed PTVS. I don't know what version it was, only whatever I downloaded from the site.

I downloaded 1.1 and tried to install it - it said that I had to remove the old install with add/remove from control panel. I did that, but it still complains that PTVS is installed. Short of attempting to reinstall VS, what else can I do?

Does it still show up in VS's Help->About or in Tools->Extension Manager?  If it's completely gone from there I'd suggest opening an admin Visual Studio command prompt and running:

msizap T {6BC9E8A5-6AEE-4BD7-9C52-AFA087FF7B48}

That should remove all traces of it.

It wasn't listed in either place. Anyway, thank you, that command solved the issue!
