The big problem is that you are specifying paths as 
'C:\MinGW\x86_64-6.3.0-posix-seh-rt_v5-rev2\mingw64\bin' rather than any of:

  - r'C:\MinGW\x86_64-6.3.0-posix-seh-rt_v5-rev2\mingw64\bin'
  - 'C:\\MinGW\\x86_64-6.3.0-posix-seh-rt_v5-rev2\\mingw64\\bin'
  - 'C:/MinGW/x86_64-6.3.0-posix-seh-rt_v5-rev2/mingw64/bin'

So \x86 for example is being treated as a hex character with a value of 
0x86.
