#-166 Device install function: DIF_REGISTER_COINSTALLERS.
#E057 Registering coinstallers failed. Error 5: Access is denied.
#E157 Default installer failed. Error 5: Access is denied.
#I060 Set selected driver.

Are you using a Coinstaller? If so, can you tell if the inf settings are correct, and/or the DLL exists?

Actually m loading a bus driver... no coinstaller... but using an inf file... it works fine for most of the PCs...!!!

Hello,

If the driver installs okay on most machines and not on a few, it would seem to indicate that there is some sort of permissions related issue that is different on those few machines.

A few questions are:

Are the operating systems exactly the same?
Is it being installed via shared resources?
When the install works as expected, does the log still refer to the NULL driver?

Thanks for your reply PeterBritton,

Yes

Is it being installed via shared resources?

No

When the install works as expected, does the log still refer to the NULL driver?

No, It says

#I056 Coinstallers registered.

#-011 Installing section [USB_Device.NT.Interfaces] from "c:\windows\inf\oem26.inf".
#I054 Interfaces installed.
#-166 Device install function: DIF_INSTALLDEVICE.

But on other PC(Problem)...

# E057 Registering coinstallers failed. Error 5: Access Denied.
# E157 Default installer failed. Error 5: Access Denied.

After googling around i found the problem is related to the windows registy permissions...
But still i am not able to figure out the solution for this issue...

Please help,

Thanks,

Hello,

A URL link to the webpage that gave details of the registry permissions, might be useful.
