Problem with v0.98


New member

After I installed CrystalControl 0.98 beta i got the following message when tried to run the application: "File PDH.DLL is linked to NTDLL.DLL that wast not found in RtlStringFromGUID" (freely translated from the portuguese windows version)

Things I tried (and has not worked):

re-install CrystalControl
re-install Windows 98
re-register the NTDLL.DLL
put NTDLL.DLL in the CrystalControl program folder

Please help, anyone!

CC 0.96 works fine here but I got this weird message: "Floating point division by zero"; everytime I run it.

My fault... CC shouldnt be using PDH.DLL under Win9x.
Ill fix it in the next version.

Weird other poeple havnt had the same problem though.

Yeah... quite weird. Maybe it's the Windows version. Perharps people are using 98SE, i'm using 98 retail OEM. I got the some problem in the computer of a friend that was using the same type of windows.

My regards

All my fault :(

I just checked and it is using DLLs it shouldnt be.
The installer was also getting a few things wrong.

I need to do more beta testing myself under win9x.

Well, actually, I'm having the same problem.
I'm running WinME, and 0.96 worked perfectly. Installing 0.98 I get the following error (in a DOS box, obviously):

Installing CanIO Port Service...
Sys Location: "C:\WINDOWS\SYSTEM\canio.sys"
OpenSCManager failed!
Please report this error

Then, when attempting to run 0.98 (which obviously won't work w/ the installation error, but hey... ya gotta try!):

Error Box #1:
C:\Program Files\CrystalControl\CrystalControl.exe
A device attached to the system is not functioning.

Error Box #2:
The PDH.DLL file is
linked to missing export NTDLL.DLL:RtlStringFromGUID.

Any thoughts? Possible fixes? Wait for the next version?
