To activate PluralEyes 3.5 with a PluralEyes 4 serial, follow these steps:
- Download and install PluralEyes 3.5 as a trial. You'll want to use this installer: Mac / Windows
Launch the PluralEyes 3.5 application once the trial is installed
When asked for a serial number, enter your PluralEyes 4 serial number and click "Register"
- You will not be able to register PluralEyes 3.5 using a v4 serial within the installer. Only after PluralEyes 3.5.11 has been installed as trial can the program be activated.
