If I recall correctly a 32-bit application can only see 32-bit ODBC sources, so you must use the 32-bit ODBC utility (C:\Windows\SysWOW64\odbcad32.exe) to define the source. I have this scenario on my 64-bit Vista workstation. From Access 2007 I can only see the 32-bit version of my Oracle ODBC source, not the 64-bit version of the source. Access 2007 is a 32-bit application.
Hope that helps, Johan.

I have a 64 bit windows 7 machine.... There are two locations to create ODBC connections: This article says a bit http://support.microsoft.com/kb/942976 32 bit \Windows\SysWoW64\odbcad32.exe 64 bit \Windows\System32\odbcad32.exe Does it matter if the ODBC connection is done on 32 or 64 bit? Is there a difference? When I try and create an ODBC connection on 64 bit there are no drivers displayed? Very confusing Thoughts? Thanks
