MS said that some programs for RC1 may not work for RC2,
but it's up to the manufacture to update the programs,
which they will be doing soon, you would think, since this release,(or something close to it)
will be sent to the RTM's in november, and dell, HP and the rest will need to configure there new box's for Vista, so they will need to have some anti virus program running by then, nero claims they will have there stuff ready for vista soon, and there will be a free trial, I just hope they really work on this 64bit
program thing alot more, I think it will force the progams to support 64bit
and yes it will work on a 64bit CPU
