CardExchange may switch from the Licensed version to the Demo version when the software detects a change in the computer's hardware identification.
A CardExchange license can be activated on only one computer at a time. Each license includes 4 reactivations, which can be used to reactivate or transfer the license to another computer.
CardExchange licenses are assigned on a one-license-to-one-computer basis.
When a license is transferred to another computer:
The license is activated on the new computer.
The previous computer loses its license and changes to the Demo version.
If you need to use CardExchange on two computers at the same time, you need two separate CardExchange licenses.
CardExchange uses a Machine-ID to uniquely identify the computer.
The Machine-ID can be generated using hardware information such as:
Network port MAC address
Hard disk drive (HDD)
USB dongle
By default, CardExchange uses the MAC address of the network port to generate the Machine-ID.
Many modern computers have two network ports. If you switch between network ports, the MAC address detected by CardExchange may change.
As a result, CardExchange may detect the computer as different hardware, which can cause the license to move between Machine-IDs.
To avoid license issues caused by changes to the network port, we recommend using one of the following options:
Option 1 – Use HDD-based Machine-ID
Use the 4-MachineID Exchange Utility (Alternative - HDD based).
MachineID Exchange Utility – HDD Based
Option 2 – Use a USB Dongle
You can also activate the CardExchange license using a USB Dongle.
CardExchange License Activation with Dongle
Using either of these methods can prevent issues caused by changes to the computer's MAC address.
Reformatting the computer can cause CardExchange to require license reactivation.
To avoid using one of your 4 available reactivations, back up your CardExchange license file before reformatting the computer.
The license file is stored in:
C:\Users\Public\Documents\CardExchange\License
Before reformatting:
Open the folder above.
Back up the .iserv file to a safe location.
Reformat the computer.
Reinstall CardExchange.
Restore the backed-up .iserv file to the same folder:
C:\Users\Public\Documents\CardExchange\License
This allows you to restore the existing license after reinstalling CardExchange.
Situation | What Happens | Recommended Action |
| License transferred to another computer | Previous computer loses its license | Use a separate license if both computers need CardExchange |
Network port changed | Machine-ID may change | Use HDD-based Machine-ID or a USB Dongle |
Computer is reformatted | License may require reactivation | Back up the .iserv file before formatting |
A CardExchange license is intended for one computer at a time and has 4 reactivations. Avoid unnecessary reactivations by keeping the Machine-ID consistent and backing up the license file before reformatting the computer.
