Attempted a PHP update which hung as before.
It looks like Local can not write to your Windows temporary directory, which will affect its ability to copy and unpack downloads:
Warning: Temp directory isn't writable: C:\\Windows\\TEMP/\nError
If you run Local as administrator (close Local, right-click the app icon, choose “run as administrator” — should give Local broader filesystem access, not the same as running as your current admin user), do downloads succeed?
If that doesn’t work you could also try checking that the C:\Windows\Temp folder is writeable by your current Windows user.
The other factor that could affect this is a full disk, but I think you already ruled this out earlier (“730GB free”).
I have raised the mysqld issue several times
@codemonkeynorth Thank you for your reports, I replied to your thread here:
the 8.0.16 version in 9.1.1 did not have this issues
Newer versions of MySQL that Local ships with require updated DLLs on Windows. Local tries to install these but we’ve seen installation get blocked, as in the current thread. Manually installing the DLLs as described above can help, as it did here to unblock the initial MySQL errors.
If you continue to see errors please feel free to reply in the other thread you started.
