AIMMS cannot find dongle after undocking laptop

Summary

After undocking a laptop from the docking station, older versions of the Sentinel driver cannot find the hardware key that protects your AIMMS license.

Symptoms

When your laptop is connected to your docking station, you can startup AIMMS, using a license that is protected by a hardware key (dongle). However, when you use/start AIMMS when your laptop is not connected to the docking station, AIMMS can no longer find the hardware key. It is even possible that this issue still appears in the most recent version of the Sentinel driver, in which SafeNet has addressed this issue.

Cause

AIMMS uses the Sentinel driver to locate the hardware key. This issue is known by SafeNet, the developers of the Sentinel driver and they have solved it in versions 7.4.2 and higher. However, if you have installed previous driver versions, these installations can still cause the described problem. Uninstalling older driver versions, does not always solve the problem.

Resolution

To make sure all old driver versions are completely removed from your machine, you should run the following program from SafeNet:

This program removes all Sentinel entries from your machine. Note that it can also remove older AIMMS installations. You will be notified by this, so if needed, you can reinstall these old AIMMS versions after you have finished the steps in this article. The AIMMS installation files can be found in the download area of our website.

After you have run the cleanup program, please install a Sentinel driver version with number 7.4.2 or higher. Version 7.4.2 can be downloaded from:
