The Architecture Mismatch error occurs when you try to use a 64-bit DSN with a 32-bit tool, or vice versa. To fix the error, you can try the following steps:

  1. Check if the tool you are using is 32-bit or 64-bit using the task manager
    • Open the details tab.
    • If the "Platform" column isn't visible, right click on any column header, and choose "Select Columns."
    • Enable the "Platform" column, then click OK.
    • Find your tool in the list, and you will be able to see whether its 32-bit or 64-bit in the "Platform" column.
  2. Open the appropriate DSN administrator
    • If you are using a 32-bit application, go to C:\Windows\SysWOW64 and run odbcad32.exe
    • If you are running a 64-bit application, go to C:\Windows\System32 and run odbcad32.exe
  3. On the system DSN tab, add a brand new DSN with a unique name (to avoid a naming clash between 32-bit and 64-bit System DSNs).
  4. Try connecting again from using this new DSN.
