Chaos Corona for 3ds Max > [Max] I need help!

Error while selecting Corona as a Renderer and then it crashes

(1/2) > >>

Skullflower:
I am using Corona 8 and 3ds Max 2023.

I am getting this error every time I press F10 and try to use Corona as a renderer instead of Arnold.

Then 3ds Max crashes.

How can I fix it? I feel like I'm not going to finish my project anytime soon as I am stuck here.

TomG:
Can you try ensuring you are logged in to the Chaos License Server before changing to Corona, and let us know if that resolves it?

maru:
Yes, there is a known issue sometimes causing this in specific cases. We are aware of it and the fix is top priority for us.

The solution is to sign into the Chaos License Server first, and only then start 3ds Max and set Corona as your active renderer.
Here is how to do it:
Close 3ds Max
Open this link in your internet browser http://localhost:30304/
Sign in with your Chaos account
You should see a "successful activation" message
After completing the above steps, start 3ds Max and set Corona as your renderer

For full activation instructions, see: https://support.chaos.com/hc/en-us/articles/4642369149585

Hi Guys.

I have the same problem here.
What happens:

Workstation 1:
Everything worked smooth. Just updated to Corona 8. Works!

Workstation 2:
Updated to Corona 8. 3ds max 2020 and 2023 crashing when Corona is selected as renderer.
When I open http://localhost:30304/ it says there are no licenses available.

I installed the Chaos License Server manually. But no luck here.

I have multiple licenses on one account.
Both machines are basically the same. Win 10, 3ds Max 2020 + 2023

Help!

This part is causing the issue:

The crash appears if the user is not signed in to the license server, or if no licenses are available.
To make it work, you need to be signed in the license server and you need to have some available licenses there.

If you have licenses under your account, but they are not showing in the license server, as the first step please make sure that you are logging in with the correct email address.

If that doesn't help, please contact us here: https://support.chaos.com/hc/en-us/requests/new

We are working on a hotfix for this right now and it should be released really soon.
As a temporary solution I can recommend downgrading to Corona 8 non-hotfix: https://drive.google.com/file/d/1-e6yJpgtlQ4w6W8D2yNURvDF5CNHDXn2/view?usp=sharing
