Now, I know this is not necessarily the place to ask, but what is the difference between the Business and Technician Editions? Have they not worked out the kinks in them, or is there a special dance you have to do to get the different 'Per Computer/Per Technician' deal? Personally I'd love to support Piriforms' development, but I'd like to know some details on pricing and terms and such.
I'm just curious, as I've been using CCleaner on a USB stick for quite a while, and it checks for updates just fine on its own, though I do have to manually download the ZIP and unzip the files.
