You can reinstall UFT3.0 by placing the UFT 3.0 CD in your computer and it should start by itself. If it does not start, click on Start, Run, Browse and then select the CD drive and double click on Setup. When the run screen comes up, click on OK.
Be sure and install UFT as an upgrade to an existing version. The Setup program will find the existing version to upgrade (if you have more that one copy of UFT on your computer, make sure the selected copy is the one you wish to upgrade).
BACKUP -- BACKUP -- BACKUP before you start the upgrade.
