Hi chasgl1,
Are both licenses for the same version/package of TestStand? If so, why not have the other worker use the new serial number to activate TestStand. This way each installation of TestStand is activated with a different serial number.
If this isn't a valid solution please call into support or contact your sales representative and we can work through this further. You won't need to uninstall.
