You are using pip version 7.1.2, however version 8.1.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

Done!

It's trying to uninstall V0.31 before installing V0.34, but it can't uninstall the old version since it's currently using pre-processors shared library which makes it so that it can't delete that file while V0.31 is running. The only way I can think of fixing this is to load the shared library when M3D Fio needs it and unload it when it's done with it, so this is something I'll have to fix in M3D Fio.

As a temporary workaround you can kill OctoPrint manually which will kill M3D Fio so that you can install the update.

taskkill /IM pythonw.exe /T
C:\python\Scripts\pip.exe install https://github.com/donovan6000/M3D-Fio/archive/V0.34.zip --user
START "" "%SYSTEMDRIVE%\python\pythonw.exe" -c "import octoprint;octoprint.main()"

hmm without doing what you suggested, I restart my computer and go back to fio to check the version it is now showing 0.34 latest.... not sure if this means it is installed properly? but I did see Muele's calibration button which was not in 0.31 version. So I think it install ok...

[donovan6000]

I guess it updated to V0.34 somehow. The next version of M3D Fio makes it so that the shared library gets unloaded when M3D Fio is done using it, so that should prevent anyone from experiencing this issue in the future.
