We currently do not officially support any 64-bit OS and we don't currently have a 64 bit version. However the current ExaminIR will probably run ok as a 32 bit app as long as you use gige. The firewire drivers don't support 64bit. At some point in the future we would like to produce a 64-bit build of ExaminIR but there is no firm timeframe for that to happen at this point.
