Please clarify if you are really referring to KORD for MSFS 2020.
SODE is not included in the installer for MSFS 2020, so it's just not possible you would see an error from SODE or the SODE installed when installing KORD for MSFS 2020. The only version of KORD that comes with SODE is the P3D4 version.
Are you maybe referring to the FSDT Live Update telling you your SODE was outdated, so it directed you to the SODE page to install it, so you downloaded it and updated it, and you are getting this error from the SODE INSTALLER ?
