WampManager doesn't start... (no replies)

Windows 10
Wamp64 3.1.0

Fresh install. Double click on added wampserver icon on desktop... get the windows complimentary "do you want to allow this app to make changes to your system?" I choose yes... a console flash and then nothing.

I go to the wamp64 directory from the console. Do:
$>wampmanager

and same result.

I've deleted and reinstalled all of the VC redistributable installations (2005-latest, 32 and 64 bit versions). Restarted my system after this and still this problem.
How do I debug/fix this?

thanks!
