‘Windows cannot find the Microsoft License Terms. Make sure the installation sources are valid and restart the installation.’

If Windows Setup reports this error, it means that an XML file was used but contained no (or the incorrect) Product Key. Some Windows installers require a Product Key to be specified (e.g. Win8, SVR2022, etc,).

You must ensure that a suitable Product Key is used if the install method uses an XML file (e.g. E2B, agFM).

Note that Windows trial or evaluation versions use a different key from the standard generic installation keys. For these trial\evaluation versions you must use the correct Product Key in the XML file. If you cannot find a key that works, then install without using an XML file (e.g. using Ventoy or Rufus) and then run Produkey from NirSoft to discover the Product Key that was used.

New! Ventoy for Easy2Boot v1.0.97 now released!
