"The service name is invalid ............" - 64-bit Driver problem
I'm trying to get a driver to work under 64-bit Windows 7 Pro but am not having any luck.
The driver is a modified version which will allow my EPROM programmer and software to access the Parallel port under 64-bit Windows (the default driver for the software only works under 32-bit Windows and works fine if I boot the same PC into 32-bit Windows 7).
The driver is called glpntdrv.sys (the guy who created this 64-bit version of the 32-bit driver says that it works on his 64-bit Win 7 installation).
I've copied this to c:\windows\system32
The above directory is in my default windows PATH (I've even tried copying it to c:\windows\system32\drivers (which is NOT in the PATH!) but that didn't of course work either)
The permissions appear to be okay (although it doesn't have a permission for trustedinstaller (does it need it?).
However, when I start up the software for the EPROM Programmer it errors saying that it's can't access the driver
If I go to the command prompt and type:
net start glpntdrv
I get the error:
"the service name is invalid"
I'ver tried rebooting and going to the menu via F8, to do this:
“Disable Driver Sign Enforcement” (which at the moment needs to be done according to the guy who revised the driver for 64-bit)
but still no luck. For some reason the driver is acting as if it's invisible.
Any ideas please anyone? This is driving me nuts.
Thanks
