Hi Calude,

You can activate Registry Reviver on your computer easily by following the below steps:

1. Open Registry Reviver
2. Click on the key shaped ‘Register’ button in the top menu bar of Registry Reviver.
3. Click on the text that says ‘Click here to enter your key’. This will bring up a new window where you need to paste your ‘License Key’.
4. 
5. Now open the purchase confirmation email that you received right after your purchase. You will see your ‘License Key’ specified in this email. First you need to select the ‘License Key’ and then copy the text.
6. Next you need to go back to Registry Reviver and then place your cursor in the text box beside ‘License Code’. Once your cursor is in this box, you can click on the Paste Code button to paste the code you copied.
7. 
8. After you have successfully copied and pasted the ‘License Key’ into the product, all you need to do is click the button that says ‘Register Now‘. You will notice that the ‘Register’ icon will no longer appear in the top menu bar. 

Similarly you can activate the other 2 licence codes on two different PCs.

Lokesh
