LDRA Test tools: FlexLM error -8, Invalid license key

07-May-2026

Cause

This issue is usually caused by the license.dat file being modified. Improper editing of the license file can invalidate it.

If you edited the file to add ports or other information, make sure that no other parts of the file were accidentally changed.


Solution

Download the license.dat file sent to you and replace your existing file. Be careful not to alter its contents.
