Andor3 issue connecting camera

[Sandeep Kumar Malu - STFC UKRI via Tech-talk <tech-talk at aps.anl.gov>]

Hi All

Andor3 driver is not able to detect the camera on Windows. I am using IOC bundled with the ADAndor3 driver. Camera is streaming in Andor SOLIS. Ironically, when I run listdevices.exe (created on ADAndor3 build). I get what I am supposed to get

Found 1 Devices.
Device 0 : NEO-5.5-CL3

In andor3 constructor, AT_InitialiseLibrary returns success. I have added AT_GetInt(AT_HANDLE_SYSTEM, L"Device Count", &DeviceCount) for debugging before connectCamera() . Looks like it has not detected the device itself (Device ID is 0)

Found 0 Devices.

2022/03/09 06:41:00.641 andor3:andor3:  camera connection failed (6)

Below are the EPICS versions I am using

Base - 7.0.3

Asyn - R4-43

ADCore - R-3-12-1

ADAndor3 - master(0cfa8b6) [I also tried SDK3.15 branch]

FYI, I have added Andor SDK3 (from manufacturer) dlls in the environment path.  The observation is camera works with standalone executable (listdevices/binTest/rateTest) but not with ADAndor3 IOC. Any Idea where I am going wrong?

Many Thanks
