Important Notes for Installation

Cannot coexist with Office (bitness mismatch): If you have 32-bit Microsoft Office installed, the 64-bit ACE provider will not install (and vice versa). You would need to use the matching bitness or install the ACE provider in "silent" mode with the /passive switch.
Provider name after installation: Once installed, your connection string should use:
```
Provider=Microsoft.ACE.OLEDB.12.0;
```
Alternative (Newer Provider): For better compatibility with modern systems, consider using the Microsoft Access Database Engine 2016 Redistributable (provider name Microsoft.ACE.OLEDB.16.0). You can download it here: Microsoft Access Database Engine 2016 Redistributable (select AccessDatabaseEngine_x64.exe).
