Certain environments (Windows Server 2016+, Windows 10 Enterprise) allow both if you accept the warning. This is not recommended for production due to instability.

Cause: Your application’s architecture does not match the installed provider. Fix:

By default, Microsoft prevents side-by-side installation of different bitness versions of the ACE provider. To bypass this, use the passive or quiet command-line switch.

Cause: Standard GUI installer conflict. Fix: Force the installation using the command line method in Part 4 (passive mode). However, be aware that this can destabilize Office. Back up your registry first.

AccessDatabaseEngine_x64.exe /quiet

Once installed, the Microsoft.ACE.OLEDB.12.0 provider is ready to use.

If you are using SQL Server:

Open 32-bit PowerShell (located at C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe) and run the same script.

Expected result: No error message about missing provider.


You can test using a simple PowerShell script.
