Installing new FSUIPC4 version over older version

[Watcher]

I have downloaded the the 4.30 version of FSUIPC4 for FSX ready to install. I have an older, unregistered, version installed. Should I just let the installer install over the old version? I intend to register the new version and would like to know the best way to do so. Any help with these two questions would be much appreciated.

Yes.

I intend to register the new version and would like to know the best way to do so.

Simply select the registration options in the installer when it asks, then fill in the fields. There's no other way, so there's no "best way" or "worst way".

The version is irrelevant to registration, provided you use FSUIPC4 keys with FSUIPC4 and FSUIPC3 keys with FSUIPC3.

There's also a much more recent, interim, update available in the FSX Downloads announcement above. Currently we're up to 4.323.
