Commuter License Manager gives a “time tamper” error (Windows 10 users only)

Date: 3/1/16


Version Affected: 13.0


Version Fixed: N/A


Issue: Using the DNASTAR commuter license manager on Windows 10 elicits a “time tamper” error message. This message occurs due to an issue with the Sentinel licensing software used by the DNASTAR license manager. We are actively working with the Sentinel software team to resolve this issue.


Resolution: Until the issue is resolved, you will need to install the Lasergene commuter license manager on a different (non-Windows 10) computer, or downgrade your Windows operating system to Windows 7 or Windows 8. Please contact DNASTAR at 866-511-5090 or for assistance.
