You need to download and install our License Delete Utility at the license manager url.
Then run the utility on the computer that you want to remove the license from. The utility will automatically pick up the license code that was installed on the computer. Note: Version 2 and below cannot use this utility. All license codes that was purchased prior to version 3 have been re-released for upgrading to version 3.
After you use the license utility, you can activate as normal on a different computer using the code you used in the utility.
Please not that the utility cannot remotely remove or revoke codes from other computers and only the computer it is run on.
