With one exception, I don't really mind having to the response code. It's a bother to be sure, but so are all those serial codes that are printed so small and hard to read. The one thing that bothers me is what if these companies that sold me software goes out of business and my harddrive crashes. Or I get a new machine. Anthony assures that they won't leave us hanging and that's probably more than we would get from Microsoft. And CL is actually a little more generous than some of the others using similar schemes. XP of course requires you to register within 30 days. I have Microsoft Office. (The next to last one. Can't remember what it's called.) You can only install that on one machine. And if you have to reinstall, you have to get a new confirmation code within 50 uses or it quits working. (I do think that should have been stated on the box.) And if you have to install it more than twice in two years, they start acking questions. I chrashed the first machine. Not my fault. It was due to the silly way Compaq implemented their Quick Restore with a partition. Then I got a new machine and Microsoft wanted to know how many machines I was installing it on, and whether I had removed it from the other machines. Many I was a little too touchy, but I did resented it. And they weren't exactly awful or anything, but if you're not doing anything wrong and someone questions you like you are. I guess you get touchy. I'm not sure, but I really don't believe they would let you also install this one a lap top. And then ZBrush has the same sort of security system. And of course there's Lightwave and with that silly dongle. So that brings me back to my main concern. Most companies don't plan on going out of business. And here I have several very expensive - for me - software packages. But what happens if they do and if they didn't have a plan in place. It does make me a little nervous. If I bought a lisense for a product, I should be able to use it even if the company has gone belly up. Of couse things change and life isn't perfect. Look at 8-tracks and vinyl records and CED video and Laser Discs. None of those companies care if we can use their products after they stopped making them. Kevin
