Hi,
I’m hoping this is something simple I have overlooked, but I
can’t figure it out yet…
I have a 64-bit driver that won’t load, and fltmc load Drv says
“The system cannot find the file specified.”. When I check for
file/registry activity, the load only goes though
CurrentControlSet001\Drv and queries ObjectName value - absolutely
nothing else related to the driver is seen in the output.
It is not a digital signature issue, that is the only thing I
can safely rule out. The driver is installed via Inf method.
Any ideas? The only thing I can think of is unsupported APIs on
the 64-bit OS, but that should pop a box saying so.

Hi.
Have you checked the registry for the altitude information?
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\YourDriver\Instances\YourDriver0

Yes, I checked that as well. Present. Using the same INF as for the 32-bit version
(which works).
The registry key CurrentControlSet\Drv is not even touched during fltmc load Drv (or
net start Drv).

Hi Dejan!
It would me better if u provide some extra info. about ur driver’s driverentry routine.
This problem can also come if u r trying to open a file/ directory / registry key in your driver entry and the operation fails.
It can also come if u have tried to create a symbolic link for a control device object in ur driver entry and so on…
There r n no. of possibilities…
Try debugging ur driver with a debugger and find out the exactly the point where ur driver entry stops and returns a Failure status.
^Happy Debugging^

The DriverEntry point does not get called at all.

If DriverEntry isn’t called, then there is most likely an undefined
symbol (or possibly a dependent DLL load that fails.) In general, MM
will write an errlog message in that case - are you seeing anything in
the event log?
Barring that I fear you’ll end up doing binary search (e.g., checking an
empty “nothing” driver to ensure it is the driver binary that is the
issue, not the registry configuration, then cutting or adding pieces
until you isolate the failure cause.)
These can be the most frustrating problems to track down (I remember
once where we found that driver load would fail from FAT for a boot
start driver because the name was not 8.3. It would work fine on NTFS,
but not on FAT. And not if it was system or auto start.)

This i a blind guess, but it happened to me already:
You copied the driver to System32 using some 32-bit application,
like Total Commander. Because of 32-bit app, the file copy has been
redirected to Windows\SysWOW64, that’s why the system can’t find the
driver.

Had that problem, but I used the INF method this time.
