Anyway, with two strikes against it, I’m afraid it’s ‘Revo Uninstaller’ time. Sorry Russians – it’s a hard way to learn.
Learning can be difficult for many people. The giveaway here states clearly that it’s for a 1-computer license, so expecting the key provided here to support a portable license is not reasonable (note that this license difference is described in the agreement you must accept before you get to the point in the installer where you can change the default single-computer installation to a portable one). Since the application is try-before-you-buy the fact that the installer (the Genery and SoS installers are now identical) offers to install the portable option for a trial is hardly surprising.
So that’s one strike for them and one for you.
