This is a release of the Transact's Virtual Serial Com Driver for Window7-64.
It has completed Microsoft's quality test and has been signed by them. 

It is targeted for Windows7 and Vista (64 and 32 bit) However, XP can also run this but installation might have to be done after printer plug-in as a driver replacement, as XP does not have the pnputil utility.

Before connecting any printers please read TUSerialInstall.rtf and if the printer must remain configured as USB Composite then Vista Install Composite.rtf shows how this is done. If printers had already been connected, it may be easier to revert a test PC to a restore point rather than trying to clear all the places that knowledge of a USB device is kept by the operating system. If that is not possible then the driver replacement option in Driver Manager can be taken.

At install time the COM port number is automatically assigned by the operating system. If the number needed by the application is fixed, then a TransChangePort utility is provided to make this change. Install and port changes only work when run in administrative mode.
Additionally, a batch file showing the minimum commands needed for this reassignment is provided for use in custom install scripts.

Uninstall is done by using Driver Manager and selecting uninstall on the virtual port.
