As soon as you create a HTMLTexture(EX9) vvvv crashes!
I am encountering the same problem with HTMLTexture(DX11). I checked that it did not crash if it was opened in vvvv_beta_38.2-4278_preview_x64
Looks like the online installer still uses a corrupt addons.zip file as was also reported here Beta39 offline addons zip is corrupt
So simple workaround for now is to use the offline installer until the online installer links are fixed.
