You can open the SysWOW64 folder by pressing Win + R, typing:
C:\Windows\SysWOW64
and pressing Enter. Alternatively, open File Explorer and enter the same path in the address bar.
Once the folder opens, copy the dao360.dll file into it. If Windows prompts for administrator permission, click Continue to complete the copy. If the application still reports that the DLL is missing, you may also need to register it using regsvr32 from an elevated Command Prompt.
