Radmin Support Center

Error message: 'Invalid license code' appear when the entered code does not correspond with the pattern of a license key.

First of all please make sure that the key you enter is correct. Radmin license key starts with RADPR.

Another reason for such error message is that you might be using proxy server (or firewall, or ISA) and it doesn't allow the outbound Internet traffic to our activation server and you can not activate your license code. In order to avoid this you please make sure that port 80 (TCP) is open for outbound traffic. In case it is not you can manually activate Radmin offline, remotely or manually.

Please refer to Radmin Help file or online guide for detailed information:

• Radmin manual activation
• Network activation guide

About manual activation:

• Enter your license code into registration field (don't press OK).
• Choose checkbox "Manual activation".
• Save *.request file
• Go to activation server.
• Upload your *.request file.
• The activation server will return you *.license file.
• Save it on your computer.
• Go to activation box again, choose "use license file" and specify a path to your *.license file received from activation server.
• Press OK.
• You copy is registered.

Remote activation:

You are also able to activate license code remotely from the local PC with Radmin Viewer. To do this open the Viewer on the local PC, right click on connection icon of the target PC and choose "License Code Transfer".

The 'About' window displays an INVALID! error

This message means that the current activation was corrupted due to a hardware replacement or OS reinstallation (or some major updates, such as Windows 7 to 10), so you should:

1. Delete this branch of the register:
   HKEY_LOCAL_MACHINE\SOFTWARE\Radmin\v3.0\Shared\Parameters\XferParam
   For 64-bit systems, the branch of the register is as follows:
   HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Radmin\v3.0\Shared\Parameters\XferParam
2. Restart your PC.
3. Reactivate Radmin Server.
