Overview

Customers with an active Flex Terminal Emulator annual subscription will receive an updated license code upon renewal. This code is delivered via email as part of the renewal letter once payment is processed and is sent to all technical contacts currently registered with FlexSoftware.


To ensure uninterrupted operation and to prevent expiration warnings from appearing for end users, administrators must update the license code on all Flex Terminal Emulator installations.


Location of the License Code

Flex Terminal Emulator stores its license code in the Windows Registry at the following path:


HKEY_LOCAL_MACHINE\SOFTWARE\FlexSoftware\FlexTerm\License


The license value in this key must be replaced with the new code provided in the renewal letter.


Updating the License Code

Updating the license code consists of replacing the existing registry value with the newly issued one. This process can be performed manually or automated across managed Windows devices.


Recommended Deployment Methods

Administrators may use any Windows device management platform capable of distributing registry updates, including:


    • Microsoft Configuration Manager (formerly SCCM/SMS)
    • Microsoft Intune (if Registry modifications are permitted)
    • Group Policy Preferences
    • Third‑party Windows endpoint management tools


The update procedure typically involves deploying a script or policy that overwrites the existing registry value with the new license code.


Example Deployment Steps (General)


    1. Extract the new license code from the renewal letter.
    2. Create a script or configuration item that writes the new code to:

HKEY_LOCAL_MACHINE\SOFTWARE\FlexSoftware\FlexTerm\License


    1. Deploy the update to all devices with Flex Terminal Emulator installed.
    2. Verify that endpoints have applied the new license by checking the registry or launching the application and choosing File>About.


Post‑Update Validation

After deployment, it is recommended to confirm:


    • The new license code is correctly written to the registry.
    • Flex Terminal Emulator launches without displaying expiration warnings.
    • Any devices that were offline during deployment receive the update when next connected.
