Hi,

I've installing the VSTO SE latest beta on the XP machine with VS 2005, Office 2007 B2TR and VSTO v3 CTP. I uninstalled the VSTO v3 CTP before installing VSTO SE. The add-ins show in the available projects, but when the VS creates a new add-in from a template and I try to compile it I get an error:

"The "GenerateAndPersistAppInfoTask" task failed unexpectedly.
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.VisualStudio.Tools.Applications.Runtime, Version=8.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
File name: 'Microsoft.VisualStudio.Tools.Applications.Runtime, Version=8.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'"

I've tried to un-install and install the VSTO SE a several times, but the problem is still there. Now I just saw in the readme for VSTO SE that if I had VSTO v3 CTP installed I will have to re-image the whole machine!!!? Unfortunatelly this is not an option for me. This is my primary dev. box. Is there any other way to fix the installation?

Thx... Alex

Having VSTO v3 CTP on the machine is a known problem. I blogged about this at the end of this post

You might get lucky if you completely uninstall all VSTO2005SE, VSTO v3 CTP and VS 2005, then install VS 2005 and VSTO2005SE again.

Umm... this is not an option for me. I know you can do better than that :)

Is there any way to get whoever created a setup for VSTO v3 CTP to write a clean up script?

Thx... Alex
