I want to download Python Tool. When I clicked Tools -> Get Tools and Features, I also get error "Unable to locate Visual Studio Installer" and I click okay on the prompt there was another error message "Operation is not valid due to the current state of the object".

I tried all of the suggestions from this following post and the errors persist.

Could anyone shed some lights?

    Hi @Ziqun Liu ,

    Like Anna mentioned in the post you shared, you can try to manually remove VS Installer and then install a new VS Installer(no need to remove VS). The steps are:

    Close VS and VS Installer => navigate to C:\Program Files (x86)\Microsoft Visual Studio\Installer => rename the Installer folder to Installer_backup => download a new setup file from here: Downloads => double click to run the new setup file => a new VS Installer will be installed(no need to remove or modify VS)

    If the Installer folder doesn't exist, try to directly download a new setup file and install it.

    If manually reinstalling VS Installer doesn’t work, please try to directly open this Installer folder: C:\Program Files (x86)\Microsoft Visual Studio\Installer, scroll down, find the setup.exe file, double click to run it. VS Installer should launch correctly. You can install Python tools by clicking Modify. This is the same to click Tools => Get Tools and Features.

    If this still doesn’t work, please feel free to let us know.

    Best Regards,
