Can I run PerfectIt 3 and PerfectIt 4 on the same computer?

No. PerfectIt 4 will automatically uninstall the previous version. PerfectIt 4 is a much better product. However, if for any reason you want to switch back, you can uninstall PerfectIt 4 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.
