Hello folks,

even with a stub it won't go much further (as expected).

Set the service in registry to 'manual start' type (3).

I intentionally returned 0x0badc0de "magic" from MmLockPagableDataSection()
stub to see the usage with related API calls MmLockPagableSectionByHandle(),
MmUnlockPagableImageSection() etc.

Microsoft docs:

https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/wdm/nf-wdm-mmlockpagabledatasection

Anyway, the next problem is IoQueryDeviceDescription() being a stub.

https://source.winehq.org/git/wine.git/blob/0aa6f8e2ea1e3f2e852bef1a07d0d1f983870150:/dlls/ntoskrnl.exe/ntoskrnl.c#l1824

Tidbit:

The app installer needs to be run in 32-bit WINEPREFIX (WINEARCH=win32).
In a 64-bit WINEPREFIX it actually installs a 32-bit kernel driver which is
stupid because this can't work by design on Windows. While Wine allows this,
the driver can't be started because the service entry has no explicit driver
path (syswow64) and Wine assumes 64-bit service when searching for the
executable.
