Everytime I Render a view it starts calculating the cgi and then it gets stuck at preparing 5.6%, eventually it says its finished but its not. When I open up render settings again I get the following error message
"Warning, cine render by maxon add on has unexpectedly close Archicad should be restarted. "
p.d. It happens with the custom rendering scene I have been using for the past year and also archicads default render scenes
I can't render at all, the preview comes out in the render settings window but the actual image does not. I tried Marquee with several areas of the project but still no luck.

i am having the same trouble in archicad 20 build 5011. when i choose to preview or render a scene that message pop up
i think everything happened after installing adobe premiere. have you found a solution so far ? . i found if set CineRender.exe to run as administrator (right click> compatibility>change setting for all users ) at least it stopped giving another error for maxon engine on startup
Jan's problem was fixed by unchecking the Grass Setting in C4D.
He was using a preset that had it on and since he had an area about a mile long with grass C4D was hanging while processing all of those grass blades.

i have been trying for so long.
So far the only thing worth mentioning is that windows system restore works !!!
Unfortunately on my other pc system restore was disable.
for that pc i have tried everything. uninstall, repair, copy cinerender folder from my working pc ,no grass enable dejrolon - thanks for trying to help- nothing . when trying to preview a render or choose to render the message " CineRender by MAXON add-on has unexpectedly closed." appears and suggests to restart archicad
p.s i also noticed that cinerender.exe doesnt run in taskmanager> processes even before i try to make a render, while on my restored working pc its there the moment i launch archicad 20.
ok i think i found it after a long long struggle.
i think after reinstalling repairing Visual C++ Redistributable Packages for Visual Studio 2013
which i downloaded directly from microsoft the problem was solved. now cinerender loads in the background and preview and rendering with maxon engine work fine .
I think this problem should either come down to
- the RAM not being enough (the model is too detailed), so try to render a much smaller area first, and see if that helps.
- or a known issue with cinerender in general. You can read more about it here.
Let me know how it went.

I've had this issue on AC20 for a while now. I don't think it's a ram issue, I've got plenty and it happened one day out of the blue, then started a few month later on my laptop.
I've been getting around it by hitting render (getting failed render) then as quickly as possible re-rendering. It seems cinerender takes too long to start but once it's running you can jump on the back of that last startup.
Personally I think due to a win 10 update, hence the delay of the issue between devices. Re-install of software should fix the issue, but this workaround works for me at the moment.
Versions 10 to 23
Metabox Prime-X P775DM2-G (Clevo),

512GB SATA 3 M.2 SSD,
Win 10 64
I know this is an odd solution - I can't explain why it worked, but for me it did and maybe it'll help someone else out too.
I kept getting the same "cineRender by Maxon add-on unexpectedly closed" error message, and tried EVERY suggested solution I could find (including totally uninstalling and Archicad and re-installing) and nothing worked.
But then I had a weird idea and....
....I turned my VPN off.
Voila! It started working working immediately and has worked ever since!
Hope this helps save someone else from going through what I went through today!
