There are many ways to find your xplorer² unlock key:

If you reached this page using any of the Upgrade menu commands, xplorer² should have already opened the license file for you in an editor window, please look for it on your desktop and copy out the full license key, then paste it in the website form. Your v2.x key looks like this:

88|0.0|X2.3|1|24.09.10|30|Joe_Bloggs|some@email.com|Usax9A
NRezzwlQsv11jmth|sisnotavalidkeyTonDBVZ|OQciJ4FDqivrb2oSS4

If you own the ultimate edition, your key will be a little bit longer and the reference should be X2UL.3
