# Error: License Authentication Failed

## NOTE: This is a legacy issue for RollBack Rx / Reboot Restore Pro 12.7 May 2024 releases The issue has already been fixed on later builds of RollBack Rx Pro and Reboot Restore Rx Pro -- August 2024 builds and newer)

**Issue**

A warning message appears on the upper right side of the screen with the following message

***"RollBack Rx Pro / Reboot Restore Rx Pro license authentication failed. You may be a victim of counterfeiting!" ***

This is even after it has been successfully activated and is still showing as activated on the Home (main menu) and under About

**Cause**

About once every couple of days, RollBack Rx/Reboot Restore Rx Pro will contact the license server to authenticate its license. If the license authentication attempt fails, this message appears. Possible causes would be either being on a VPN/ firewall during the authentication attempt.

**Solution**

This generally will auto-resolve if a connection to the license server is established.

To force-check it:  
\- First, make sure you have an internet connection  
\- disconnect from a VPN (if you're currently connected to one)  
\- Go to start \> run \> cmd  
\- type in this command

shdcmd.exe /chkactivate /u administrator /p password

(leave the password blank if you don't have a RollBack Rx Pro/Reboot Restore Rx password)

\- reboot the PC  
\- once rebooted the message should go away

**Note**  
\- no functionality is lost with this warning message. It will not revert to the demo even after several failed attempts
