STVD MCU Selection List Empty dao360 re-register not work anymore

Hi ST support team,

     I'm using STVD version 4.3.12,  no matter create an empty project or open the existing project. 

 The MCU selection in Project Setting always empty.  But the same STVD installation package works in some other computers.

     My computer is 64-bit x64-based processor, running Windows 11 Enterprise Version 24H2.

     I tried re-register dao360.dll in administrator CMD, there was a period when it could be resolved, but I'm not sure if it was due to Windows updates or some other reason. Now it's not working anymore.

 CMD command:

Regsvr32 /u "C:\Program Files (x86)\Common Files\Microsoft Shared\DAO\DAO360.DLL"

Regsvr32 "C:\Program Files (x86)\Common Files\Microsoft Shared\DAO\DAO360.DLL"

 I have the same problem with Windows 11 (64-bit). I use ”Oracle VM VirtualBox“ with Windows 7 32-bit to solve this problem, running well now.
