Unfortunately I do not have enough reputation to comment yet. But the response marked as an answer sent me in the right direction.

I did not see anything in my path related to HTC Sync Manager, though I had it installed. I'm not working with my HTC device at the moment, and only had the sync manager installed to help with driver issues. Once uninstalling the HTC sync manager this issue went away for me.

Hope this helps someone else.
