8-22-2009:     After a few automatic updates; I am experiencing Mach3 crashes as well along with bizarre graphics.  I feel like I am using pre-beta software.

Is Mach going to check into this problem or are they going to wait for Windows 7?
-----------------------------------------------
I am using Vista 64-bit and it works like a champ.

Just follow the Vista instructions provided by Artsoft in the download section

System:
Intel Core i7 920 Nehalem 2.66GHz LGA 1366 130W Quad-Core Processor Model BX80601920
ASUS P6T Deluxe/OC Palm LGA 1366 Intel X58 ATX Intel Motherboard
G.SKILL 12 GB (6x2GB) DDR3 (PC312800)
Seagate Barracuda 7200.11 ST31000340AS 1TB 7200 RPM SATA 3.0Gb/s 3.5" Hard Drive
ZALMAN VF900 – CU 2 Ball VGA Cooler

 

i spent an entire day beating myself up trying to get vista64 to play nice with me.. I crashed it probably 20 times with my various array of bizarre video hardware capture devices and it still refuses to update properly from windows update site.. (now im using a hack update installer.. on a legit box.. pffffffffffff)  not to mention having to hack to get back into my own pc cuz i got locked out by a funky update glitch ... double pfffffffffffft...)

see this stuff, and be warned, happens randomly to vista 64...  will work great and suddenly you reboot after an update and you poked.. kill automatic updates.. do it.. save yourself this pain..

anyway i digress...

Typically the things i figured would NEVER work all did.. rhino, matrix . and yes, mach.. worked great.

I have never tried it on vista32 but since it will work on this POS operating system I am  pretty willing to bet it will work on that one too..

this exersize has been a fun way to waste a day of my life.. will be downgrading back to xp32 this weekend
