We use WiX (http://wix.sourceforge.net) to generate the installs, which is a bit different than the build in VS installs. The basic idea is still the same. You use a Custom Action that calls an EXE in your install that looks for a certain "/uninstall" command line argument and then performs the deactivation.
So in our case, the DeployLX.exe startup code looks for /uninstall and calls each of the installed components and asks them to uninstall.
The code to uninstall looks like this:
Try
Dim info = New LicenseValidationRequestInfo() With { _
' If they don't have a license we don't want to prompt for a serial
DontShowForms = true
}
Dim license = SecureLicenseManager.Valdiate(Me, Nothing, info)
If license IsNot Nothing Then
SecureLicenseManager.Deactivate(Me, Nothing, nul)
End If
Catch ex As NoLicenseException
' Ignore no license
End Try
try
{
var info = new LicenseValidationRequestInfo(){
// If they don't have a license we don't want to prompt for a serial
DontShowForms = true;
}
var license = SecureLicenseManager.Valdiate( this, null, info );
if( license != null )
SecureLicenseManager.Deactivate( this, null, nul );
}
catch( NoLicenseException ){} // Ignore no license
