I have Elements 2020 and can not get camera raw version 12.4 installed 220.127.116.111. Update is gray and not available, the file i downloaded is ver 12.4 and it installs apparently ok but when i look in the help it is still ver. 18.104.22.1681
Download and install, Import and export, Problem or error, Windows
That standalone software (not a plugin) can convert a whole folder of your raw files to the DNG format that your PSE2020 can read and edit in the ACR converter. An additional batch operation, but free and with the same quality.
