I have a Deep Rybka4. Tried to install the update 4.1.
Installer exe downloads.
On trying run, after permission to proceed, up comes Acceptance of terms, accepted.
It requires somewhere to go,suggests Mozilla Firefox.
I suggest Program Files/Chessbase, (where I have Rybka4 as Engine 12),
Up comes the terms of licence again. If I accept then a background window stops installing and goes.
If I do nothing, then nothing happens.
Do I tryProgram Files/Chessbase/Engine12?
All I see is the terms of Licence, unable to see the installation occurring, until I switch it off by accepting the terms again.
