I'm just asking this out of curiosity, since I already bought the second license, but I recently discovered that some utilities are licensed differently, and I almost payed double there by not asking.
I have A1Click Cleaner on my desktop machine. I wanted a copy on my netbook, so I bought a second license. Did I really have to do this, or would it have been permitted to just put a second copy on my second machine without paying again. (Both machines are for my own non-commercial use only.)
