Aspen Hysys License Checkout Failed -

full text

Here is the of the typical error message you might see when an Aspen HYSYS license checkout fails , depending on the version and license manager (e.g., AspenTech Licensing, FLEXnet, or SLM):

• Step 1: Navigate to the following directory on your C: drive: C:\Program Files (x86)\Common Files\AspenTech Shared\Licenses
• Step 2: Look for a folder or file named cached or borrowed. Delete these temporary files (do not delete the main .lic file).
• Step 3: Restart the computer and try again.

4. Diagnostic and Troubleshooting Methodology

• Service Stagnation: The lmgrd or AspenTech vendor daemon services may have stopped running on the server due to a crash or server reboot.
• License Expiration: The license file has a hard stop date. If the date passes, the daemon refuses all checkouts.
• HostID Mismatch: The license file is cryptographically bound to a specific hardware signature (HostID/MAC Address). If the server’s network card is replaced or disabled, the license file becomes invalid.
• Token Exhaustion: All available floating licenses are currently in use by other users.

• Check your license file: Open it in Notepad. Look for INCREMENT HYSYS_Process or INCREMENT HYSYS_Steady_State.
• Compare with your version: HYSYS V14 requires V14-specific license tokens. A V11 license cannot check out a V14 feature.
• Solution: Request an updated license file from your AspenTech distributor.
