Can I run PerfectIt 4 and PerfectIt 5 on the same computer?

No. PerfectIt 5 will automatically uninstall the previous version. PerfectIt 5 is a much better product. However, if for any reason you want to switch back, you can uninstall PerfectIt 5 and get the previous version from our website again. Your computer will remember your old version, and you won’t have to enter your registration information again.
