Typo in path? ""Could not find suitable TLS certificate

Due to what I susped to be a TYPO in a hard-coded PATH in the requests package, the certificate is not found in Windows 10.

Requests Version is 2.14.2 from anaconda 4.4.0 for Windows 64bit.

## Expected Result

Pip/Conda work using TLS.

## Actual Result

Okay, something messed up my system environment variables. Never mind.
