When calling SecureLicenseManager.Deactivate, the result is always false.
If SecureLicenseManager.Deactivate(_license, Me, Nothing, Nothing) Then
MessageBox.Show("Deactivated")
End If
if (SecureLicenseManager.Deactivate(_license, this, null, null))
{
MessageBox.Show("Deactivated");
}
Cause: Not Passing a Valid License
You are not passing an activated license to the Deactivate call.
_license = SecureLicenseManager.Validate(Me, Nothing, Nothing)
If Not _license.IsActivated Then
MessageBox.Show("Oops, no activated license found!")
ElseIf SecureLicenseManager.Deactivate(_license, Me, Nothing, Nothing) Then
MessageBox.Show("Deactivated")
End If
_license = SecureLicenseManager.Validate( this, null, null );
if( !_license.IsActivated )
MessageBox.Show( "Oops, no activated license found!" );
else if( SecureLicenseManager.Deactivate( _license, this, null, null ) )
MessageBox.Show( "Deactivated" );
See How-to: Deactivate a License when Customer Uninstalls for a sample.
Cause: Bug in 3.2 R3140
If you have a valid activated license you may still get false when using the latest released version 3.2 R3140. We've fixed the issue and it's available in the latest release.
