Hi,
    I'm wondering if someone can help me troubleshoot this.
I installed Mach3 on a Windows7-32 bit machine carefully
following the instructions to reboot after the install and before
running Mach3.  However, when I attempt to launch the DriverTest
program nothing happens. DriverTest doesn't seem to run at all.

I don't know what to do now.

Did you set the driver test to "Run as Administrator"?

Thanks. No.
That was the problem.

Scott at ArtSoft asked the same thing.
When I rightclicked on the icon for DriverTest and selected "Run as Administrator",
it ran just fine.

So problem solved.
