Well, I figured out my problem. Darn "autocorrect" and copy & paste! :)
It was indeed the quotes that were the issue, but not in the way I thought.
I had copied and pasted the command line into WPP from an Outlook email message. Outlook had "autocorrected" the quote characters to fancy "open" and "close" quote characters instead of just plain standard quotes. So that's what I pasted into WPP.
Once I manually typed in the quote characters on the command line field in WPP so they were true quote characters, the install worked just fine.
