My vsto file is not recognized by Office 2007

Question

I have created an add-in VSTO for powerpoint 2007 but my .vsto` file is not recognized (apparently the right format is .ppam) but when I build it creates a .vsto file, how can I get a correct file ?

Are you building a [VBA Add-in](http://msdn.microsoft.com/en-us/library/office/gg597509.aspx) or a [VSTO Add-in](http://msdn.microsoft.com/en-us/office/hh133430.aspx)? — SliverNinja - MSFT, Aug 08 '12 at 14:09

Since you are using VSTO, you need to use a Visual Studio Setup Project to install the application. Here is a deployment guide for VSTO 3.0 and one for VSTO 4.0 that should be helpful for you.

Also, but default when you build a VSTO solution on your development machine - it installs itself automatically. In order to uninstall it - you have to clean your solution.
