Does anyone know if Fritz11(or any other Fritz program) can be installed onto another computer using the same disc?....Is there anything that only allows it to be installed once?  I've had other programs that do that, so I'm just wondering.

Well, there is a code you must enter, but if you give it to that person, there should be no problem. There is only one thing I don't know: when you play online on Fritz, then you may be caught... Only when yoo both play there.

You'll be fine.. just use the serial number again.  You bought it so  you should be able to put it on any computer you want.  Of course it should be your computer or one you use frequently.  I have it installed on two computers at my house and on my computer at work.

Ok...thanks for the input, I appreciate it. 

fritz 11 sounds cool...

I have fritz 11 in my pc. recently i bought a rybka 3 and installed it in my pc to make this two software play and to determine who is really the stonger one. But to my dissapointment that everytime i installed rybka fritz 11 became unuasble and vice versa. Any one who can explain to me why it is happening?

how can this 2 software play against one another in just one PC...
