From LANDesk, we've found these are the ones that are almost critical, many users of the FHC will want to try some of these before buying, others who may not be able to afford them will find them useful when working their databases with nFS/Family Tree.
Ancestral Quest 12.1 (after install, check for updates and install those)
Legacy 7.5
Family Insight (latest update is 2012.5.5 and it may need to be updated after you get it from LANDesk)
RootsMagic 5 (Open software after installing from LANDesk, it will say if it needs to be updated).
Arkiv Digital. Get from fhc.familysearch.org, it's not on LANDesk but being on that other link it is still OK to get that way. Replaces Genelines 2, Genelines was bought out last year and this is the new package that replaced that, good especially if you have a lot of patrons that need to look up Swedish ancestors.
Don't install MSIE 9 yet, use version 8, and install Chrome as it self-updates saving you headaches that way. IE 9 is quite buggy still and does not quite work with FamilySearch properly in some matters.
Install FamilySearch Indexing on all machines, the new patron check-in form mentions Indexing now as a reason for visiting the center, they sent that as a PDF to directors yesterday.
Be sure the latest versions of Flash, Adobe, and Java are on the machine, Chrome will update at least Flash on a regular basis so that may be less of an issue if you run Chrome browsers. While Flash is less of an issue with FS than before, it is still needed by some other family history websites.
One more item, there is a 'virtual machine' that displays the Scottish OPR data and installs the whole database on the machine, that's still only 600mb anyway, won't even need the CD after that, and if more than one person wanted to view it there wouldn't be any wait for that because it would be on each machine. It's one of the 'FamilySearch' items and says 'virtual machine' in one of the columns on LANDesk. If you have less than a 7mb connection, you'll need to do them one at a time due to the file size stated.
If Sophos isn't on any of the machines, it can be downloaded from LANDesk. However, it should be there, look for it on the list of installed programs and if not there, get it from LANDesk.
