I have three computers in the house, running XP Home, I want to upgrade them all to XP Professional but I have read that I can only install Win XP Pro on one system without infringing the activation rules. If I bought and paid for legal XP Pro software surely this does not mean I can only install it on one computer! Bye the way I recently installed Adobe pdf software on my computer that had already been installed and activated on a friends computer, I had a little trouble but activation was successful on my third attempt could I hope for this with XP Pro?
VoG™ - a tad over the top - no help was asked for - more a question of was it true that it couldn't be done, I read.
MS does not permit multiple installs of a single copy. Most other OS vendors do - many Linux versions either come free, or have free versions. Linspire, for instance allows multiple copies in a single home, and will also very soon have a free version.
In fact it's MS that are out of step with many of the rest of the OS suppliers, so it's not an unreasonable thing to question their policy. The fact that they're the dominant supplier of OSs doesnt mean that their policy is the only commercially viable one, nor the only possible one. It's just their choice, and they will stand or fall by the choices they make.
As a different comment - I don't think you would even find it worthwhile to upgrade your XP home copies, in any event.
What you actually bought and paid for was a licence to use the software on a single computer. Look at it that way, and it's easier to understand. You didn't buy the software - Microsoft owns that - you bought a licence to use it.
Your use of Adobe Acrobat is illegal under the terms of the relevant copyright legislation, regardless of the fact that you were able to use your friend's installation key.
I still think it is morraly wrong of any company to expect that, if some one has three computers in his house he needs to buy three lots of whatever. After all I only have one TV licence and I have 7 TV sets and two video recorders in my house and that is OK. It's just Uncle Bill ripping us off as are all those other companys who make people buy duplicate programs for the computers we run under one roof.
I am not happy and will never be so about the big swindle.
