Error: "A protection device or license is required" (Remote Desktop Connection) (Pervasive)

Description

NOTE:

Replacement devices are no longer available.

This issue occurs due to using Windows RDC/RDP to remote into a computer that has an Estimating standalone USB protection device. Estimating standalone USB protection devices work with a single standalone computer. They don't work through RDC/RDP (or through Terminal services). It's behaving as expected per specifications.

Workarounds

Locate the computer that has the Estimating standalone USB protection device and log into it directly.
Use License Manager (LM) instead of a standalone USB protection device. LM works with Terminal and Citrix Servers and other remote desktop technologies. If you don't have LM, contact your Sage Consultant.
