Hello,

I have a laptop win 7 home pre with 64 bit and I just wanted to download the eval copy of mach3 and lazycam beta minus the drivers for eval purposes but my machine won't allow me to save or run the file.  I downloaded it on my desktop same OS any suggestion on settings.  Same security software on both machines.

I run Mach on a Sony Vaio windows 7/64. It seems to work fine with a smooth stepper. I am still tinkering with the SS.

win 7 home pre with 64 bit

You will need 32bit to run Mach3 and you need to install which includes the drivers.
 Al far as using W7, I don't use it so unless someone gives you specifics do a search to find what the W7 quirks are.
