When I put my activation Key, I see the message: ‘All activations are used up!’

The license allows the use of the software on a single computer.
The software can be installed on multiple computers or transferred from one computer to another provided that its use is limited to one computer at a time.

The software is protected by a software activation key that allows the activation of the license on a single computer.
You can transfer the license from one computer to another at any time without limitation.

If you transfer your license from a computer to another, you have to use the same activation key, but be careful that it is necessary to deactivate the license before you uninstall the software, or format the computer.

If you have already uninstalled the software without deactivating it, you have to reinstall, deactivate and then uninstall it again.
