Q1: Is there a direct download link for just the DLL (aceoledb12.dll)? No. Microsoft does not allow redistribution of the DLL alone due to licensing. You must use the redistributable installer. Microsoft

Install 32-bit (forcing side-by-side)

msiexec /i "AccessDatabaseEngine.exe" ADDLOCAL=ALL /quiet
