Now I remember VS Revo Group does have multimachine pricing models. But I never buy them to know how this strategy is implemented. Is it different keys for each PC or special design keys that can be activated simultaneously? Well, assuming from the message sent in your mail, it seems the answer is the second one.
A little correction to the review made by Grr, yes we do have context menu integration on Revo Uninstaller. If you want to uninstall a certain program, just go to the Program Files Directory then look for folder in which you install the program and right click your mouse on it.
