This error originates from the FlexNet licensing system used by HyDraw CAD and indicates a mismatch or corruption in the local Trusted Storage (license cache) on the system.
FlexNet stores license details in a secure local repository called Trusted Storage.
The error appears when the version of the stored license data does not match the version required by the currently installed licensing components.
The main cause is an incompatible or corrupted FlexNet Trusted Storage version, often triggered by a software update, reinstallation, or damaged license files.
If the issue occurs again in the future, you may need to repeat the same resolution steps.
