My question is i just bought anydvd and it's on my main pc. Can i install it on my other computer with the key i bought or no?
In fact that's what Slysoft says to do is make a disc with the key code on it just in case. I bought some of those baby discs for that purpose.
And dont forget to keep the other comp udated with the slysoft updates too. If your second comp is not used on the internet, you can easliy copy to a jumpdrive or disk, each new UPDATED version, and just install over old version everytime you update. Smooth like butter.
