: Check Windows Task Manager for hung solver tasks such as flow.exe , cool.exe , warp.exe , or mhb3d.exe . Ending these processes can release "stuck" licenses.

Missing or incorrectly configured license path file. Causes of "Exclusive" License Failures

This is a sneaky one. If you have Windows File Explorer open and you have clicked on a .sdy or .mfr file, Windows locks that file to generate a thumbnail preview. Moldflow cannot get "exclusive" access because Windows is reading the header.

Start Menu > Autodesk Moldflow Insight/Adviser 202x > License Configuration 202x Ensure the License Mode Server Hostname are correct. and restart the software. Check Environment Variables Ensure the ADSKFLEX_LICENSE_FILE variable is set correctly in Windows. If the server is on a slow network, consider creating a FLEXLM_TIMEOUT variable to prevent the license request from timing out. Reinstall Licensing Components

Never run long analyses directly on a network drive. Copy the project locally, run the analysis, then move results back to the network. This avoids exclusivity conflicts with backup jobs and other users.

Navigate to HKEY_CURRENT_USER\Software\FLEXlm License Manager and check the ADSKFLEX_LICENSE_FILE key.

Many enterprises store Moldflow projects on network-attached storage (NAS) or Windows file servers. If the network experiences latency >10ms or packet loss, the lock negotiation fails. Moldflow's exclusive lock mechanism is sensitive to SMB (Server Message Block) protocol versions. Mismatched SMB versions (e.g., client using SMB 3.1.1, server limited to SMB 2.0) can cause false exclusive errors.

If the project is on a network drive, copy the entire project folder (e.g., C:\Temp\MyProject ) to your local SSD. Open it locally. If the error disappears, the problem is network-related (latency, SMB, or NAS locking). If it persists locally, proceed to advanced fixes.

Restart your computer to allow the SJM service to initialize cleanly. 3. Configure Local Firewall and Antivirus Exclusions

"Error 99998: Unable to open study exclusively. The study may be open in another session or you do not have write permissions."

Try opening a different project to see if the error is project-specific.

This bypasses the corrupted database lock state.
