Since Origin 2019b, Python Console depends on some of VC++ 2017 DLLs. Generally, these DLLs are installed in your system and upgraded to the new version as you install Origin 2019b or latter versions.
Somehow another application that also depends on these DLLs may already exist in your system before your try to install Origin. If so, these DLLs may fail to upgrade to the new version because of conflict or permission. Therefore, you will see the error "No Python installed" when you run Python in Origin.
