with GForce GTX 560M with latest drivers

I tried all the things listed here

https://www.blend4web.com/doc/en/problems_and_solutions.html#problems-upon-startup

thanks for any suggestions

thanks - I tried that before a but it never seemed not to work. I did it again and whereas the the blend4web button appeared on the left there was no content on the right (i.e. I could not turn it on).

I then tried install add on from file and pointed it to the same folder where I had pointed scripts to in files - and restarted and then all was well

This is windows 10
Nothing I tried so far results in the add-on appearing on the list after trying to define the scripts folder

On this release there is no blender_scripts in the CE folder - only a scripts folder which seemingly does not contain some of the specified files I see in another post where similar problem was resolved -

I pointed the scripts folder to the root of the CE folder but still nothing appears in the add ons menu after restarting blender

Thanks for any help
