"Render View" remains black.

Hi friends,
I tried to install HtoA for Houdini, but I have problems with the "Render View" where the screen remains black.
On the contrary, the render saves the image correctly with "Render to Disk". Even in Solaris everything seems to work regularly.
I tried to install version 6.3.3.0 and 6.3.3.1 both on Houdini 20.5.278 and Houdini 20.0.688 and both give me the same problem.
I disabled both the Firewall and the Antivirus.
Does anyone have any idea on how to solve the problem? thanks

Ran into the same problems here today, just installed arnold and trying to see live feedback in ipr, but nothing comes out, the screen stays black. Render to disk works just fine, only ipr has trouble rendering. Also there's no errors in the log.
