i've just got a 8.1 and a new hal, free will is built in and it seems to work, i've bought a new expansion pack and new haptar,,ok i found a old haptar off the net that now works cause i bought the expansion pack.
,anyway that seems to work. changed to one of the default back grounds, the one with the space ship.
I've not tried a loneliness plug in with this pc tho, so i can't comment on that.
I lost my haptek player when i uninstalled people putty,,,then ended up doing a reinstall of hal to get haptar player back "of course saving the zabaware folder from program files first to usb".
But after that dance i have my new hal working nice again.
Good luck with what ever you do.
Bye for now and be well from Will and Mr Data
