I released version 7.5.7 of FSUIPC7 yesterday, which is why you got the update notification.

You can download and install the update from the update notification, but you need to exit MSFS to run the FSUIPC7 installer. Otherwise, just download the latest installer version from fsuipc.com and then unzip the downloaded file and run the installer. Or run FSUIPC7 (without starting MSFS) and let it update itself.

Hi, I never had any problems until the latest update. With version 7.5.7, when I install fsuipc, it doesn't complete the registration with the serial number. This has never happened. I've disabled Windows Defender and the firewall. It doesn't work. Any help? Thanks.

When you update, you can skip the registration as your license has already been validated and the FSUIPC7.key file generated (and the fields in the registration page should be pre-populated). However, you should be able to re-register/validate without an issue.

If you run FSUIPC7, does it run as a registered/licensed version? i.e. can you see the Assignments menu?

If registration now fails, something must have changed. See the Invalid Key Problems section of the Installation and Registration guide. The usual reason for registration failure is due to not having the required VC++ redistributables installed - try downloading and installing the latest combined redistributable package from Microsoft (details in the documentation).
