Follow this process to identify the Microsoft ACE components installed on your system.
64-bit ACE Components
To access the 64-bit ODBC Administrator to check for the presence of 64-bit ACE components, complete these steps:
Note: Before you begin, make sure that the ODBC Administrator is currently closed.
- Navigate to Start, and enter C:\Windows\System32\odbcad32.exe into the Search programs and files field.
- When the ODBC Administrator opens, click the Drivers tab and look for Microsoft Excel Driver or Microsoft Access Driver.

If these drivers are present, this confirms the existence of 64-bit ACE components. - Check the version number. Typical driver versions range from 14.0 to 16.0. If neither driver is listed, check the 32-bit ODBC Administrator.
Note: It is a good idea to check the 32-bit ODBC Administrator even if 64-bit ACE components exist. This step helps avoid any possible driver conflicts.
32-bit ACE Components
To access the 32-bit ODBC Administrator to check for the presence of 64-bit ACE components, complete these steps:
Note: Make sure that the ODBC Administrator is currently closed before you begin.
- Navigate to Start and enter C:\Windows\SysWOW64\odbcad32.exe into the Search programs and files field.
- Click the Drivers tab of the ODBC Administrator and look for Microsoft Excel Driver or Microsoft Access Driver as highlighted in the 64-bit ODBC Administrator image above. Check carefully because there might be drivers with similar names, but you are concerned only with the ones shown in the example. Below is a 32-bit ODBC Administrator that lacks the specific driver that you are looking for:

If you found the Microsoft Excel Driver or Microsoft Access Driver in the ODBC Administrator launched from C:\Windows\System32\odbcad32.exe, they are 64-bit components. If you found them in the ODBC Administrator launched from C:\Windows\SysWOW64\odbcad32.exe, they are 32-bit components.
