My old computer crashed and i bought a new one, i have a copy of Vista premiem upgrade, i got a while ago and used on my old computer, my new laptop has just basic, can i install my upgrade version on the laptop without any problems? Or will there be issues?
Yes you can install it on the new one providing it will no longer be used on the old one.
You may find you can't activate it online becouse it's already activated and need to activate it by phone, the activation phone number should be displayed by Windows. Just tell them you are only using it on the new computer to get a new activation code.
