This message is printed before the installer starts a sequence of processes to check, download and install FTL.
The first step is FTLcheckUpdate(), where it checks if FTL needs to be updated, comparing the local FTL with the remote one.
If the local version needs to be updated, then FTLinstall() will download and install the new version.
If you are noticing this step is taking a long time to complete, it could be related to a slow machine, a slow internet connection or some other network issue, but we never noticed any unexpected delay.
