Transferring an Existing License To Another
Computer
As mentioned above, a license is only valid on the computer for which it was
obtained. However, a license can be transferred from one computer to another. There
are several reasons to transfer a license. The application developer may set up the
system off-site, then transfer the license to the actual computer on-site when ready.
Alternatively, if the hardware or operating system on the computer where the CNX
Gateway is licensed is upgraded, the license ceases to be valid. However,
transferring the license to another computer before the upgrade and then back to the
original machine after the upgrade avoids any possible problems.
On both the source computer (where the license is currently valid) and the
destination computer (where the license will be transferred), make sure the CNX
Gateway is installed and running. If the Gateway "Update/Transfer License" window
is not displayed, right-click the CNX Gateway icon in the system tray and choose
Properties. Click on the About tab and select the Update License button to bring up
the "Upgrade/Transfer License" window. Make sure this window is active on both
computers.
On the destination computer, create a preparation file on a diskette in the A: drive by
inserting a blank diskette and selecting Prepare Diskette. This will create a file on
this diskette which indicates who will be receiving the license. Alternately, this file
can be created on another portable media (e.g. Zip disc) or a network drive by simply
using the "Windows Open" dialog to browse for a new file location. When
transferring via a network drive both computers need read/write access to the drive
being used.
After the last step has completed, remove the diskette from the drive and insert it into
the source computer's floppy drive, and click on the Transfer License. The source
computer will read the preparation file to see which computer wants the license. It
encodes the license with the destination and writes it back to the same file on the
floppy diskette (or network drive). The source computer has now passed the license
to the file. Only the designated computer can use the license, so the CNX Gateway is
no longer licensed on the source computer.
NOTE: At this point in the transfer procedure your CNX Gateway license resides
on a file on the diskette or network drive, and not on the computer. If this file should
become lost or damaged, your license will be lost as well. Because of this, please use
the utmost care while performing this transfer.
Bring the diskette back to the destination computer. Click on the Transfer License
button. The computer reads the license information off the diskette and transfers the
license to itself. The CNX Gateway should now be licensed on this machine.
