O&O DiskRecovery needs to be licensed for each computer, in other words, you need to acquire a license for each computer where you use O&O DiskRecovery. You are not allowed to transfer this license on another computer.
If you would like to implement O&O DiskRecovery in your company or as a technician for your customers, then please contact one of our resellers or our Sales Department.
If you do not enter a valid license key, you can use O&O DiskRecovery as test version. The test version allows you to search for lost files, yet it cannot restore them. Restoration is only available in the full version. Should you have any questions, please contact our Support Team.
