Hi,
I see "C:\Program Files (x86)\... in the path for the reader - which is a clue that you have 64 bit windows installed as this is the folder for 32 bit apps on win64 installations.
Therefore, I deduce that you are running a 64 bit version of windows - is that correct?
Assuming my deduction is correct, I'm sorry, but I have to point out that Mach3 is not supported on 64 bit versions of windows.
Please refer to the main Machsupport.com web page where it says:
Mach3 Minimum Requirements:
* 32-bit version of Windows 2000, Windows XP, Windows Vista, or Windows 7 Operating System
I am unable to assist with problems arising from the use of an unsupported OS version.
For running Mach3, you need to use one of the supported Win32 versions of windows.
