“Hardware Fingerprint Has Been Modified and License Cannot Be Used” – TEKLYNX Error Message


This article explains the TEKLYNX error message “Hardware Fingerprint Has Been Modified and License Cannot Be Used” and details how to fix the underlying problem that caused it to appear.


This message indicates that the license for BACKTRACK, LABELVIEW, CODESOFT, LABEL ARCHIVE, SENTINEL, TEKLYNX CENTRAL, and BACKTRACK has been invalidated resulting in the software being unable to function. A Hardware finger print error occurs when there is a break in licensing. It can be caused by multiple reasons.

Possible Reasons:

  • Recent changes in hardware configuration may have prompted this error message. (change in operating system, hard drive, network card, hard drive partition, CPU, memory size, etc.)
  • An in-version upgrade to Windows 10 may cause this
  • Other Windows updates
  • A roll-back of a virtual machine to an earlier state
  • Using a cloned image of a PC with the software activated


You must deactivate the software for that license (i.e. serial number) BEFORE reactivating the license. The standard method is slightly different for singe user/workstation licenses versus network licenses.
