Title: A Blue Question sign in device manager win7 32
Post by: Stefanus on March 02, 2019, 06:26:34 AM

Hi',
I have installed licensed  mach3 on my pc win7 32bit ram 3gb, and it is for my plasma cnc, keep getting this blue question mark in device manager. My bob is cnc4pc c35s with lpt port connection to pc. I have ran driver test, was fine, i did turn off power management, screen saver, win fire wall, it is only for mach3.  Did i miss something, ?anyone can help me to solve this same problem?
Thank you

Stefanus

Go into command prompt with administrator rights and paste and add the below registers.

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 3 /f

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 3 /f

Restart the computer for the changes to take effect.

(I got this from post by another forum member)

 A Blue Question sign in device manager win7 32 just means "driver is NOT digitally signed" with Microsoft.

The 2 registry patches are to prevent Mach3 crashing because some new Win7 automatic updates will try to disable the "unsigned drivers".

After applying the two patches you can safely ignore the ? sign.

Do the same for the next reg add line.

After applying the two patches you can safely ignore the ? sign. My win7 system has  the blue? sign too. Only Windows XP systems will NOT have that blue? sign.
