No change - still not starting.
Thanks for your patience. I'm hopeful we're close, just haven't found the right hangup.
What I did:
Followed your link, downloaded the installer, ran it. Since the runtime was already there, it offered to do a repair. I let it and it completed successfully. Tried to start the wampapache64 service -- no go. Same msg in Event Viewer as seen previously.
