Fatal error: License does not contain necessary information - company name and product name ...

You will receive such error message if the license file that should be loaded is not a valid license file.

You should simply make sure that you are loading the correct file. A license package consists of two files: a INFO file and a license file named .ht<PRODUCT-NAME>.zl.

The license file is prefixed with a dot. Some operating systems may hide such files automatically! So make sure that you see this file and use this in your configuration!

The INFO file simply holds some information in readable form.

It is a common mistake to rename the INFO file to .ht<PRODUCT-NAME>.zl which will end in this fatal error message.
