Dear Mr. Zahradnik,
that was almost clear, thank you.
But I don't understand why I need to uninstall it from machine 2 to continue developing it on machine 1.
>>>>> Because it is "Single PC Usage License". Technically, it would work just fine - there is no protection. But legally, you buy rights with the license, and the rights are for single machine at a time.
I have developed it without a licence on machine 1 and ran it on machine 2 (for 30 Min. of course).
Why can't I continue doing it this way with only one licence on machine 2?
>>>>> Technically, yes. Legally - no, the explanation is above. Think about it this way: Anybody who wants to really USE the component for something (not just development), eventually needs to get away from the trial license and buy something. In theory you should only use the trial only to evaluate whether the software is worth buying; then buy it; and then do the real development. We do not care much if you don't buy it while you are developing on first machine, because, as I said, one needs to buy a license for real usage anyway. At that moment, the license restrictions really come to effect, and you need to pick the right license (or combination). If you bought just one 105001, put one machine into production, and continue development at the same time, you would simply be violating the terms of "Single PC Usage". The short description with the license says it: "You can develop on one computer, but must purchase licenses for each other computer that you plan to deploy to.".
2. If I get the 105003, do I have to uninstall it and put it on another machine so that for example my partner can continue developing it on his machine?
>>>>> I do not fully understand the question. Only one license can be installed at a time on a given computer (technically enforced); and each machine for non-trial use must have appropriate license installed, for legal use. So, for example, if you buy 1 piece of 105001 and one piece of 105003, you can cover two computers: one can be in any role (105001 allow either development or production=runtime usage), and one only for development. Or, if you buy just 105002 (which comes to almost the same price as the combination of 105001+105003), you can have one computer in any role (development or production, but most likely this will be the development computer), and then any number of production computers.
>>>>> 105002 is the most popular buy, because most organizations are fine with just one developer machine at a time, and welcome the option to deploy to any number of production machines. Only organizations that indeed require multiple developers working with the component at separate machines will consider the combination with 105003.
