Hello, I am trying to install Arnold for Houdini, and I am using the standard version 20.5.332… but I’m getting an error (Command Exit Code: -1073741819).

The render doesn't start in Render View or with MPlay, but if I set the output to JPG, instead of IP, it does save the image correctly...

I’m on Windows 11. I’ve tried with both the (Python 3.10) version and the standard version, but it’s the same issue...

I moved to 20.5.278 and try to instal HtoA 6.3.3.1, but same issue...

However, I saw that others have the same issue, and it has remained unanswered...

I think the important part is this:

No licenses could be found to run this application. Please check for a valid license server host

I know... but the liscence from Arnold is installed and everithing is ok if i check the server.
And the render works if I set the output to JPG, instead of IP, it does save the image correctly...

I have the exact same issue.

License installed and working and renders fine in Solaris.

Same as William, setting the output picture to a file works fine but fails to find the license when setting output picture to ip.

Also asking in Arnold forums with no luck just yet.

has this been fixed by now? still the same issue on a vanilla install of houdini 20.5.410 py310 and arnold 6.3.5.1_r8826918

I have the same issue for a long time, can't use Arnold in Houdini 20.5 in Mplay/Preview. Works fine on an older version of Arnold and Houdini. And also works with rendering to files. No watermarks or things like that, it reads the license correctly. I don't really know if it's a Houdini or an Arnold problem.
