Description
On shared lab PCs or RDS systems, one user can run the application without license issues, but other users on the same machine cannot obtain a license or see “no license” errors. The cause is often related to per‑user configuration, profiles, or environment variables pointing to different license settings.
Solution
- Identify working vs non‑working user context
- Log in as the user for whom licensing works and note:
- License configuration (server/port or license file path).
- Environment variables (if used).
- Any per‑user config files.
- Log in as a failing user and check the same settings.
- Log in as the user for whom licensing works and note:
- Confirm the information in the Restrictions and Settings tabs of the LS
- Ensure that all users within the designated group can successfully connect to the license server.
- Verify that the ACDNMON.INI file contains the correct LS credentials as specified in the Settings tab of the LS.
- Confirm that users are appropriately assigned to the relevant programs by checking that their usernames or groups are properly selected in the Restrictions tab of the LS.
- Test with a clean profile
- Create a new test user with the same group membership.
- Log in and start the application:
- If licensing works, differences between the test user and failing users are likely due to stale or conflicting old settings in those profiles.
- Reset or align failing users’ configuration:
- Remove or rename old per‑user license config files.
- Delete the files in %APPDATA%\Advanced Chemistry Development folder and launch the software to allow the application to recreate the configuration from global defaults, or copy in the known‑good configuration from the working user, adjusted to be non‑user‑specific.
- If the previous steps were not effective, consider converting the license type from named user (per user) to seat-based (per computer). To proceed, please submit a request to support in order to obtain new registration keys for the License Server.
