The official LogmeIn installer for windows XP and server 2003 does not work.
The old installer worked perfect , you can download it from here..
But after installing LogMeIn on Windows Server 2003 , I got Your Computer Offline error .
Me and my friend Nouh could fix it by the following steps :
# open Internet Explorer -
# goto Tools - Advanced
# scroll to the end of it
# enable TLS 1.0
# disbale SSL 3.0.
you're done !
