An error "Your browser's security settings for the zone it chose for this connection are not compatible with the HP SIM popup menu"
HP Systems Insight Manager v6.3 installation have been done on an Windows 2008 R2. So this is an internet explorer 8. (there are some troubles with internet explorer 9)
And Security options have been set to medium-low.
Same problem with Firefox
SIM63_hotfix_2011_Aug_win.exe have been installed also
Problem is solved with SIM63_hotfix_2011_Oct_win.exe (ftp://ftp.hp.com/pub/softlib2/software1/pubsw-windows/p1002362299/v73061)
