- 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.
It seems the location of operating system programs was not changed when the OS became 64-bit native. So OS binaries stil reside in System32, even though they are 64-bit binaries! SysWoW64 is short for Win32-on-Win64, and is the location of 32-bit binaries on a 64-bit version of Windows.
Why isn’t it like this?
- 32-bit binaries go in System32
- 64-bit binaries go in System64
