Dealing with License Key Errors

NeuroExplorer requires either a physical USB license key or a software (cloud) license key to operate.

Sentinel USB license key:

Dinkey USB license key:

Make sure to install the correct version of NeuroExplorer.

If you purchased a USB license key:

• Download and install NeuroExplorer5Setup64.exe.

If you purchased a cloud (software) license key:

• Download and install NeuroExplorerNexCloudSetup.exe.

Sentinel drivers need to be installed so that NeuroExplorer can communicate with Sentinel license keys. These drivers are installed when you run NeuroExplorer setup (NeuroExplorer5Setup64.exe).

Dinkey license keys or cloud license keys do not require Windows drivers.
