Download and license
The full and trial versions of PerfectIt are nearly identical.
You can use all of the built in Styles and Consistency Checks in the Trial and Full version.
You cannot connect your CMOS account for access to CMOS styles with the Trial version.
The trial is time limited so that you cannot use it when the trial is over. So, when you buy, you should use your license key to unlock the trial.
You can get the full version of PerfectIt here: Download PerfectIt | intelligentediting.com.
When you launch PerfectIt, it will prompt for your registration details.
At that point, please copy and paste the license key and details that were sent to you when you bought the software into the registration form.
