Here s the steps  my non-computer-savvy girlfriend had to figure this one out for me  but unlike all the far more complicated processes one can find online  this one works    Open Control Panel Click  Uninstall a Program  Scroll down to Python and click uninstall for each version you don t want anymore    This works on Windows 7 out of the box  no additional programs or scripts required

You will also have to look in your system path  Python puts itself there and does not remove itself  http   www computerhope com issues ch000549 htm  Your problems probably started because your python path is pointing to the wrong one

you can delete it manually    open Command Prompt cd C  Users  lt you name gt  AppData Local Microsoft WindowsApps del python exe del python3 exe   Now the command prompt won t be showing it anymore  where python --  yields nothing  and you are free to install another version from source   anaconda and  after adding its address to Environment Variables -  Path  you will find that very python you just installed

It s actually quite simple  When you installed it  you must have done it using some  exe file  I am assuming   Just run that  exe again  and then there will be options to modify Python  Just select the  Complete Uninstall  option  and the EXE will completely wipe out python for you   Also  you might have to checkbox the  Remove Python from PATH   By default it is selected  but you may as well check it to be sure

Almost all of the python files should live in their respective folders  C  Python26 and C  Python27    Some installers  ActiveState  will also associate  py  files and add the python path to  PATH  with an install if you tick the  use this as the default installation  box

I know it is an old question  but I ran into this problem with 2 7 and 3 5  Though 2 7 would not show up in my default windows uninstall list  it showed up fine in the ccleaner tools tab under uninstall  Uninstalled and reinstalled afterwards and it has been smooth coding ever since

Windows 7 64-bit  with both Python3 4 and Python2 7 installed at some point     I m using Py exe to route to Py2 or Py3 depending on the script s needs - but I previously improperly uninstalled Python27 before   Py27 was removed manually from C  python Python27  the folder Python27 was deleted by me previously   Upon re-installing Python27  it gave the above error you specify  It would always back out while trying to  remove shortcuts  during the installation process   I placed a copy of Python27 back in that original folder  at C  Python Python27  and re-ran the same failing Python27 installer   It was happy locating those items and removing them  and proceeded with the install   This is not the answer that addresses registry key issues  others mention that  but it is somewhat of a workaround if you know of previous installations that were improperly removed   You could have some insight to this by opening  regedit  and searching for  Python27  - a registry key appeared in my command-shell Cache pointing at c  python python27   which had been removed and was not present when searching in the registry upon finding it    That may help point to previously improperly removed installations   Good luck
