2015 also needs to install 32-bit AccessDataengine, anycpu chooses 32-bit first , otherwise Microsoft.ACE.OLEDB.12.0 is not registered.
hanstom , a rehash question, Microsoft.ACE.OLEDB.12.0 not registered, access 2016, x64
2. About Office 2016
Still can't connect on systems with Office 2016 X64 or AccessDatabaseEngine _X64 .exe installed .
And after installing AccessDatabaseEngine.exe or office 2016 x86 , there is no problem.
Office 2016 X64 can be connected with AccessDatabaseEngine.exe.
The landlord, an old-fashioned question, Microsoft.ACE.OLEDB.12.0 is not registered, access 2016, X64
