Dear @Anonymous,
Please note that there may be compatibility problems depending on what OS you choose. Netfabb 5 is a long-discontinued product. We provide neither support nor maintenance or servicing to keep it compatible with newer versions of operating systems, or OS updates, or to fix any issues it may have had at its last release. It may continue to work without problems, but that is not, and cannot be, guaranteed.
Specifically, the licensing mechanism, a third-party component that manages licenses and functionality permissions that was used for Netfabb in conjunction with the dongles, may be incompatible with newer OS versions such as Mac OS Yosemite and up, or Windows 10. In fact, due to the product's age and legacy status, we could not even guarantee it working on systems that have been running since, outwardly untouched.
Compounding the issue is that the dongle system’s manufacturer has not released ready-to-use support material for any newer Apple operating systems. If you are running netfabb on Windows, you may try an updated driver for the dongle system. Visit https://www.marx.com/en/support/downloads?direct=driver and download and install the CRYPTO-BOX driver. Then reconnect the dongle and try running netfabb again.
However, if the dongle, or a license activation stored on it, is still not recognized, it may mean that the dongle hardware has failed and is no longer recognized by Windows. From a technical perspective, there is nothing we can do to fix this as the dongles are no longer available.
Should such installations after all fail to work, or fail to continue working, there is, regretfully, nothing we can do to reanimate them.
If you purchased your original netfabb license through a reseller, please contact them for any options of replacement or upgrade.
Alternatively, may I invite you to have a look at Autodesk Netfabb at www.netfabb.com and its 30-day trial? Not only is it a product with continued support and maintenance, Netfabb has had extensive development, improvement and bugfixing in the five major versions since. Feel free to contact our Sales team at https://www.autodesk.co.uk/products/netfabb/subscribe/contact-me for any further options.
Kind regards,
Steffen
