I'm a developer on this extension. In the marketplace tab in VSCode you can right click the python extension and select "Install another version" when you do that it will pop up a list of all the old versions of the extension. This should allow you to go back and find the version that works for your VSCode.

I know this is an old post but I recently ran into this exact same issue. It was caused by my machine having pending Windows updates that needed a restart to be applied.
Once you've reset your machine remove the C:\Python27 folder (this is important).
Rerun the installer and it should work with no issues :-)

Please provide the environment you have installed.
if windows 2008 R2, because of the rights issue, you need to cancel the installation of pip, it is best not to install in C.
