DriverEntry return question

After my driver is installed, it has discovered at DriverEntry time that the
registry has not been set up correctly, it returns STATUS_REGISTRY_CORRUPT
and the XP Home Sp2 system crashes.... bummer.

What should be returned from a driver if the driver cannot initialize and
wants to be taken out of the game?

Gak,

It depends on what kind of driver. For instance, I'd expect system crashes
if pci.sys's failed in its driverentry. Also, you need to undo what you have
done in the driverentry to safely bail out. What if you just do NTSTATUS
DriverEntry(){ return STATUS_REGISTRY_CORRUPT };?

start?

OK, I'm a lot smarter know:

WINDOWS XP SP2.
I've got a file system filter driver. It turns out that my question is
about deployment, msiexec, difxapp.

As I mentioned before the registry is not right and I need to quit. So I
probably need to back out any resources that I've acquired . At this point
my driver is not open for business, so there are no DPC's, ... etc. But
there are calls to ExInitializeResourceLite that need to be undone, etc.


HOWEVER HERE IS THE REAL QUESTION:

My deployment app (.msi file) built from VS 2005 deployment app requests
that certain registry settings be made in
HKLM....\currentcontrolset\services\myservice.

And my inf file also requests that setting values in that key as well.

I've got 2 installers for 2 very similar projects. The INF files are
virtually identical.
However, the deployment app for the working program also creates a Windows
Service. And launches it as a Custom Action. Not so in the failing
installer.

What I am seeing is that DIFXAPP causes the driver to be executed while
msiexec is running. In the working case, the registry settings are being
setup before the driver is launched. In the failing case NOT SO.

So, my driver is looking for registry settings it WILL NOT FIND, and thusly
pukes.

WHAT CAN I DO TO CAUSE ALL THE REGISTRY SETTINGS TO BE COMPLETED BEFORE THE
DRIVER IS LAUNCHED??????

can't answer the DIFX question, but you should really put your driver
specific reg values in
HKLM....\currentcontrolset\services\myservice\Parameters and leave
HKLM....\currentcontrolset\services\myservice alone
