hi Thanks for your reply
The copy I have installed I borrowed the disc off a friend. to see If I
liked Vista, so obviously the product key for that version is already in use
I have however bought a new copy of vista, and I thought I could simply
enter the product key from that disc but it says it's in use
So I'm hoping I won't have to re-install... hope that makes sense
Ah! I'm afraid that you will have to reinstall. Or return the OEM
license (if possible - depends upon the vendor's return policies) and
purchase that same type as you borrowed from your friend. An OEM
Product Key cannot be used with a non-OEM installation.
Product Keys are bound to the specific type of DVD/license (OEM,
Volume, retail, full, or Upgrade) with which they are purchased. For
example, a Vista Home OEM Product Key won't work for any retail version
of Vista Home, or for other any version of Vista, and vice versa. An
upgrade's Product Key cannot be used with a full version DVD, and vice
versa. An OEM Product Key will not work to install a retail product.
Bottom line: Product Keys and DVD/license types cannot be mixed & matched.
