If you have already got to the "Python35.dll" error, try this first: https://www.microsoft.com/en-us/download/details.aspx?id=48234
You may also want to consider installing the VC++ redist packages as well: https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads (Try the 2015 one first, if that doesn't fix it, try the 2017 one)
