Denford Software & Machines

We are having problems in running the QuickCam 4D software on our school machines

The machine is a PC running Windows 2000 on the school network. It is sited next to the Microrouter we purchased in December 05. The software is installed on the machine in accordance with the single user licence.


The software runs OK when a user with full administrator permissions logs on. However, when a student or member of staff logs on we get the following error message:-


The application failed to initialize properly (0xc0000022).

There are a couple of INI files QuickCAM4D writes to:

C:\Documents and Settings\USERNAME\Application Data\Denford
(this is true for the latest version v1.6 which can be downloaded from our website)

However, these files DON'T have to be present to run the software.
The initialisation problem must be to do with a DLL or OCX that is being used by QuickCAM 4D, which cannot be loaded up because of user permisions
Searching the Internet, I found this advice to give all users at least read access to OCX and DLLs in the system32 directory

CACLS %systemroot%\System32\*.dll /E /G BUILTIN\Users:R
CACLS %systemroot%\System32\*.ocx /E /G BUILTIN\Users:R

DLL's and OCX's to check for are:
deskey32.dll
wdrvr.dll
ntoskrnl.dll
instsec.dll
plus any OpenGL libraries eg, OpenGL32.dll - especially ones provided by graphics card manufacturer
