Steve Dower added the comment: Do you see a "Repair" option when running the installer again? If not, open Programs and Features and find Python there, double-click it and select "Repair". Otherwise, you should have a set of log files in your %TEMP% directory (sort by date and they all start

Steve Dower added the comment: Oh wow, I've never seen anything like this before. It looks like it's really confused about whether you've installed for all users or not. I wish I knew how you got into this state, because I'd like to be able to prevent it. I guess it's related to the current is

Mark Harris added the comment: Hi Steve, Thanks looking into this for me. I tried the below and ran the lines in cmd with admin privileges. Then I tried running repair again. I'm afraid when I type python in the command prompt it has the same message as before about missing python35.dll. I

Steve Dower added the comment: I was hoping that Repair wouldn't be an option after doing that cleaning. Maybe try uninstalling through Programs and Features, then run those commands again, go into the places you installed it and delete the files, and then run a fresh install. If you still ge

Decorater added the comment: Normally when you install python systemwide it installs python35.dll in %SystemDrive%\Windows\System32\. Try looking there maybe you can use regsvr to register python35.dll in the registry or find where python.exe is and copy python35.dll to there. -- nosy

Eryk Sun added the comment: No, Python 3.5 is the first version to always place the interpreter DLL in the installation directory, beside python.exe. Installing for all users does not place python35.dll in "%SystemRoot%\System32". -- nosy: +eryksun

Mark Harris added the comment: Thanks for the advice, I downloaded the Python35.dll in the file located here https://www.python.org/downloads/release/python-352/ which was called "Windows x86 embeddable zip file". With this file when I enter python.exe the program crashes. I tried Windows x86

Steve Dower added the comment: Looking at those logs, it seems like we think the per-user packages are already installed. When you go to do an all-users install, it "removes" the per-user packages, but passes in the same options as it does for the all user packages. Under the hood, these packa

Steve Dower added the comment: That's only the most recent set, and all it shows is that the per-user install didn't help. Do you have the earlier sets of install logs for the per-user install and uninstall? I'd like to see why those didn't have the effect I expected. --

Mark Harris added the comment: No worries Steve, I've managed to fix it. I uninstalled, went through regedit & removed all mentions of python. I then installed python 2.7, installed 3.4 afterwards, uninstalled python 2.7 and for some reason that worked, it is working correctly now! Thanks for

Steve Dower added the comment: > installed 3.4 afterwards Did you mean 3.5 here? If you're going to change versions, I'd at least suggest grabbing the 3.6 beta - it's *much* better than 3.4, and we've had very little trouble with the most recent version (RC is coming in a week or two). --
