Thanks for the release. A few installation issues appeared.
I did a side-by-side 32-bit install to 1.8.4 on Win10-64, so got the dialog for config file version conflict and to use the --pcp option for having 2 installs, which I did using the Windows-R Run dialog. After doing this Laz2 does not remember this was set on the previous run and to use the new config directory when it starts. I had to manually edit the startup shortcut to use the option on each invoke.
Also, it would be nice if the installer asked which top menu name/shortcut name prefix should be used when a previous installation is detected but not being upgraded and overwritten, so the shortcuts and menus from existing version aren't affected.
