Hi,
I am getting an installation problem for sample WIA scanner driver
(present in ddk sample) on 64 bit OS. I have two OS builds of XP 3790
and 3787. I could able to install the driver on 3787 and could able to
initiate the scan but on 3790 build I could able to install the driver,
but above the WIA driver KSTHUNK.SYS upper filter driver in getting
attached, due to which the scan is failing.
I want to clarify some of the issues
- In which circumstances does thunk drivers are installed ? And who
will takes care of installing the thunk drivers ? - Is it possible to avoid installing these thunk drivers from our inf
file? Or is there any other method to avoid automatic
installation of thunk drivers ? - Since the problem is arising on 3790 but not on 3787 build, does it
points out that the problem is with versions of the builds ? - The WIA scanner driver is a user mode driver which runs as a COM
service, is this is the issue due to which thunk driver is
installing ?
Regards
Abhiman.
