Failed to Decrypt License Key Received Error

When upgrading to one of the new license types, on an owned LiteSpeed Web Server license, activation fails with the following error: [ERROR][LICENSE]Failed to decrypt license key received!. This happens on versions of LiteSpeed Web Server that are 5.2.8 or earlier, when you try to activate a new 5.3-style license.

The new LiteSpeed license types that were introduced with LSWS 5.3 can only be used on version 5.3 and newer. The above error simply means “old binary cannot work with new license type”.

In our store, we clearly state that only 5.3 and above will support the new license type. The new license.key has special encryption that can only be decrypted by 5.3 or higher. Users who don't plan to update to 5.3 should not order one of these new licenses.

If you've already purchased the new license, you have two options:

  1. Purchase a yearly upgrade so that you can install the latest version of LSWS.
  2. Revert back to a license that works with LSWS 5.2.8 and earlier.

You may exercise either of these options through the Client Area in the LiteSpeed store.
