To include your company name as the verified company you'll need to purchase a digital certificate and sign the spawned updater app with your own certificate. For the purchase of digital signatures we'd recommend to have a look at GlobalSign.

Unfortunately this is not us enforcing this, this is Microsoft's security policy. It will only allow digitally signed executables to replace files under \Program Files folder.

The files you need + instructions to perform custom signing of the updater application are available upon email request.
