WinNT 4.0 Problem


New member
When I attempt to run Crystal Control v0.93 on my copy of Windows NT 4.0 SP6a, I receive the following error when it launches.

"The procedure entry point RtlStringFromGUID could not be located in the dynamic link library ntdll.dll"

I have no LCD display to connect to the unit, but I was trying to view the software to see what uses I might get from an LCD. However, I can't even get into the problem far enough to configure an LCD even if I had one connected.

The file ntdll.dll on my system is dated 18 Nov 1999, could this be out of date?
Looking for additional LCD resources? Check out our LCD blog for the latest developments in LCD technology.

Hmmm... very interesting.

Try getting the original PDH.DLL that came with NT4 and put it in your windows/system32 directory. That will overwrite the PDH.DLL that came with CrystalControl.

If NT4 didnt come with PDH.DLL, i dont think theres anything i can do. I might have to strike off NT4 as being on the supported list :(

Well, I don't see PDH.dll in our NT4 distribution or on any of our other NT4 installations, so I guess I'm out of luck. Was this tested on NT4 before now?

I havn't, and no one I know of has tried it on NT4 before, so you maybe the first.

I guess i could create a version for NT4, but it would be missing a lot of options the normal NT or 9x CC would.
