I haven't played around with OpenVPN in a while and I ran into this error during a fresh install of v.2.5.5 on a Windows 10 machine tonight. I'm beating my head against the wall at this point. I can't figure out what this error means. "Maximum option line length (256) exceeded" I could really use a hand here.

You have probably stripped out all line endings, somehow ..

Wrong. Fresh install on windows has macintosh line endings (CR)

The correct answer here was use Notepad++ -> edit -> EOL Conversion -> Windows (CR LF)
