I have an Asp.NET web application. I can call and run Teamviewer in my application when running on local.
I have a class for call and run TeamViewer.

There seems to be misunderstanding of how web works :) You need to run something on client side - not on server side. ASP.NET executes just on server side (and passes back just html markup that is interpreted by browser). For this kind of work you need a thick client - see @Damien_The_Unbeliever comment regarding security - LOL btw. Since you're already in .NET world, I recommend using ClickOnce (.NET technology that allows you to install applications from web url with just one click - provided your clients have .NET framework installed) and make small app that will do the "thick client" job for you.
