Just an FYI for those who have not updated FSUIPC to 7.4.12 yet. If you are use to FSUIPC auto-starting when you launch MSFS (by way of the entry in the exe.xml file, not by using the FSUIPC Shortcut Icon) this has been removed.
They (FSUIPC) found that when launching via the exe.xml file that LUA scripts ran up to 13X slower than when using the BAT file.
If you don’t use LUA scripts (and if you don’t know what those are, then you probably don’t), or only use a few, then there shouldn’t be an issue.
To re-enable launching from exe.xml you can run the FSUIPC installer again, select auto-start with MSFS and it should add it back in.
Further, you can just use this block and update the path.
