Vista64 compatabilty definitive list

Hi,I am thinking of moving to vista64 bit... i will eventually so it may as well be sooner rather than later.Has anyone compiled a definitive compatability list for payware (and freeware) addons?I own many, but my particular interest is with LDS767, PMDG744+F, 737NG series, Dreamfleet Baron, A36, Archer III ( don't think any of these will work due to garmin trainer problems ), DF727 plus many others.. so if anyone can point me to a list or we make one here.. it would really help my planning.Other programs I use and want to work in vista64 are... Fsbuild, Radar Contact4, AS6.5, ultimate terrain, ultimate traffic, flight enviroment, ground enviroment pro, RXP SN3308 and ST3400.Would using vista32 bit be significantly advantageous from a compatability point of view?I am trying to look to the long term, so I can live without some addons until they are updated for compatabilty at some later date. I don't mind waiting even long term for addons to catch up.Thanks is advance.Paul
