Gentlemen,
I downloaded and installed nrComm Lib v9.38 for Delphi 7 and CBuilder5
My computer is brandnew and runs on a legal version of Windows 7 professional 64 bit
I bought and installed 2 DLock PCI Express Cards both 2xSerial+1xParallel
All 4 serial ports work fine.
But I need also to control both paralell ports from Delphi 7 and CBuilder5.
In my system I see
Com & LPT ports: "PCIe to Multi Mode Prallel Port (LPT1)" and "PCIe to Multi Mode Prallel Port (LPT2)"
The LPT properties show;
lpt1-sources: I/O C010-C017 & C000-C007
lpt2-sources: I/O B010-B017 & B000-B007

So everything looks fine.

However, when I run LPT demo from Delphi 7 after checking "Active" I get "Create service failed"
It doesn't matter if I leave the address 00000378 or make it 0000C000, 0000C010, 0000B000, 0000B010.

What do I need to do get get the LPT ports running properly?

Hi Roman,

I turned off UAC and now that message has gone.
My LPT is connected to a small test board which gives me the ability to read bitd by means of LEDs but can also force the pins high/low.
But I tried addresses C000, B000 but nothing seems to work.
Any idea why not?

Hi Roman,

Problem solved.
I didn't know how to test my LPTs besides your application.
Today I was happy to find: http://www.xlentelectronics.nl/LPTTest/LPTTestUtilx64r.htm
With this little tool and my own LPT test pcb I found out that I should use addresses C010 (LPT1) and B010(LPT2).

And this runs fine also using you LPT software (in Delphi7).
