SNL update on virtual machine

Hi,

About a year ago, our SNL server was transfered to a virtual machine. I now need to update SNL manager on the server. But according to http://www.javelin-tech.com/blog/2011/04/avoiding-snl-activation-issues/ , I can't use RDP to connect and do the update without screwing up the activation process.

So what do I do? Can I simply use VNC or any other alternative to RDP and not have any problem?

Thanks
