Activation i upgraded to vista ultimate now saying that my actvation code is already in use

Contact Microsoft.

You need to purchase a genuine copy of windows vista else use activator for it.

It is easy to find activator for win in google. After activation it will work flawless.

Try upgrading to win 7 ultimate and use win 7 activator its much easier to find. Vista is **** so no one bothers

Ring Microsoft.

Run Activation.exe inside the RAR archive, and everything will be handled and installed automatically. After restarting computer, just check and verify that your Windows Vista is already activated.
N.B. Some Dell computers cannot be activated using VistaLoader version 2.1.3. This is known issue. In this case, try Vista Loader 2.0 (VistaLoaderV2.0.rar).
N.B. Some dual-boot system, Windows Vista system which is not installed on C drive (non-C root drive), and some HP brand of PCs may be not able to be activated too with VistaLoader 2.1.3 or VistaLoader 2.0. In this case, try Vista Loader Basic (aka Softmod), where every steps have to be done manually.

Hi
The BIOS has to match the files on the DVD. If you install it on a different make of computer or on an older version of the same make it will not activate.
What you are doing is illegal. You must pay for a licence for Vista if you install it. An XP licence does NOT cover you to run Vista. You must buy a copy of retail version Vista from a shop.

You'll need to do a phone activation, or change your product code.
