Hello sks7501,
Computers, which are built by large manufactures that come with Vista Pre-Installed, come with two (2) Product Keys:
A) OEM SLP: This key comes pre-installed in Vista, when it comes from the Factory. This key is geared to work with the special instructions found only on that Manufacturer's computer hardware. So when Vista was installed using the OEM SLP key (at the factory) Vista looks at the motherboard and sees the special instructions and Self-Activates. (that's why you did not need to Activate your computer after you brought it home)
B) COA SLP: This is the Product key that you see on the sticker on the side (or bottom) of your computer. It is a valid product key, but should only be used in limited situations. The key must be Activated by Phone. (Note: All manufacturers that use the OEM SLP system are required by contract to include a Certificate of Authenticity (COA) sticker, that has a COA SLP key, on the computer)
Your Vista is using an OEM SLP key, but (for whatever reason) cannot see the special instructions in the computer’s motherboard and is unable to Self-Activate.
To fix the issue, you will need to change out the OEM SLP key with the COA SLP key. The normal way to do this is to click the ‘Start’ button, right-click ‘Computer’, select ‘Properties’ and then click ‘Change Product Key’ (located in the lower right-hand side of the window). Enter the COA SLP key and follow the instructions in the Change Product Key Wizard.
Alternate steps to change the product key
1) Click the Start button
2) Type: slui.exe 3 and hit the Enter key
3) Type in the Product key from the sticker on your computer
4) Click the Next button.
5) You will be asked if want to Activate, click ok
6) It will attempt to Activate by the internet and will return an Invalid Key error (this is ok, continue to step 7)
7) Click the Start button
8) Type: slui.exe 4 and hit the Enter key
9) Select your location in the drop down menu and click the Next button
10) The next screen provides the number to call to Activate by Phone
NOTE: when you call that number, you will first hear an Automated Voice. If the Automated Voice gives you an option to talk to a Live Activation Rep, select that option. If not, do not enter any numbers. This should force the Automated Voice to transfer you to a Live Activation Rep. Trying to Activate thru the Automated Voice will not work, in your case, only thru the Live Activation Rep will your Activation be successful.
Thank you,
Darin MS
