I want to add 32-bit data sources. There seems to be no obvious way to see existing instances of these or create new ones.

How can I open the 32-bit "ODBC Data Source Administrator" window in Windows 7 64-bit?

Run the Datasource editor from this path c:\Windows\SysWOW64\odbcad32.exe.

Just a small note to Zorodache answer, if you use the search box from the start menu type the whole path to get the correct version c:\Windows\SysWOW64\odbcad32.exe.

Otherwise, you will get the 64-bit version, even if you enter odbcad32.exe in the search box.

  • @DenysVitali except, apparently, if you put the whole path in the search box, you still only get the 64-bit version. I ended up having to open a command window – Auspex Jun 28 '17 at 10:21
  • Seriously? Really strange... but I'm not surprised anymore when Windows is involved... – Denys Vitali Jun 28 '17 at 13:48
  • @Auspex for me it works entering the full path c:\Windows\SysWOW64\odbcad32.exe – Carlos Escalera Ohow Jul 17 '17 at 17:04

A 64-bit version of the Microsoft Windows operating system includes the following versions of the Microsoft Open Database Connectivity (ODBC) Data Source Administrator tool (Odbcad32.exe):

  • The 32-bit version of the Odbcad32.exe file is located in the %systemdrive%\Windows\SysWoW64 folder.
  • The 64-bit version of the Odbcad32.exe file is located in the %systemdrive%\Windows\System32 folder.

The Odbcad32.exe file displays the following types of data source names (DSNs):

  • System DSNs
  • User DSNs
