There's no need to keep version 1 of PerfectIt if you're using a newer version. So if you have both on your computer, you can uninstall version 1. To do that, you can either:
Go to the 'Start' menu. Then click the PerfectIt program group, then click 'Uninstall'.
Go to Control Panel. Choose 'Add/Remove Programs and Features'. Choose PerfectIt.
