Actual behavior

I have upgraded Python 3.6.5 to 3.7.0. Why is this still 3.6?

Have you selected the python environment?
If not please select it.
The status bar shows the default python version.
Here's the documentation https://code.visualstudio.com/docs/python/environments#_select-an-environment

It can only choose Python 3.6

This would indicate the fact that 3.7 is not in a standard discoverable directory.

• Please could you print the location of python 3.7 install directory.
• Also print the output of python --version for the 3.7 environment

Please try ring the following from command prompt and provide the output of each:

• C:/Program Files/Python/python.exe --version
• Python --version
• Python -c "import sys;print(sys.executable)"

Looks like something is wrong with the registry entries.
Please could you dump the registry entries for the following path:
* HKEY_LOCAL_MACHINE\SOFTAWARE\Python
* HKEY_CURRENT_USER\SOFTAWARE\Python

Never mind, I'm able to replicate this. The problem is with the registry entries. They do not get updated, i.e. bug in Python installer.

This issue should get resolved with #1351, as we'll not be using the registry entries in display names.

Steps to reproduce:

• Install python 3.6 in directory x
• Install python 3.7 in the same directory x
• Two separate registry entries exist for python 3.6 and 3.7 (though 3.6 doesn't exist anymore, as it has been overwritten)
