It’s important to know which kind of DSN you are suppose to check when you are Troubleshooting ODBC Connection.
If you want to check ODBC Connection on x64 system, you can check or create an ODBC Connection(DSN) for 32 Bit application and also use it for 64 Bit application.
32-bit applications will only look for ODBC connections created in the 32-bit, and 64-bits applications will look for ODBC connections from the 64-bit.
So if you want to configure DSN for 32-bit application on 64-Bit OS you will have to use:
1. C:\Windows\SysWOW64\odbcad32.exe(Used to check ODBC for Symantec Endpoint Protection Manager)
You want to do the same on 64-bit application on 64-Bit OS you can use:
Note: In case of Symantec Endpoint Protection Manager installed on 64 Bit Operating System we get confused about where to locate ODBC Connection.
So it will be found under "C:\Windows\SysWOW64\odbcad32.exe"
