Corona Corona for 3ds Max Issues

Hi guys,

We just upgraded to Corona 1.4 and we’re loving it so far! It’s working perfectly on all our workstations which run everything between Windows 7 and Windows 10. Max 2016 SP1.

However, we also have some servers that use Windows Server 2012R2 and whilst 1.2.1 and 1.3 worked fine, 1.4 offers me the following error in the Backburner server window (I have no Max license on these nodes so I can’t actually launch Max in UI mode):

The installation does the “installing additional magic” redistributable and offers no errors. I went to the Windows website and tried to update it manually but it said I already had it installed. I installed all the Windows updates I could and it runs (in a virtualised environment) Xeon E5-2670’s.

I just uninstalled 1.4 and went back to 1.3 and that worked without problem.

Any thoughts?

Can you try running Corona 1.3 benchmark on the nodes and report if it works?

Hi Ondra,

It doesn’t!

apt-ms-win-crt-runtime-l1-1-0.dll is missing!

Thanks,
Dan

Ok, I ran this for Windows Server 2012R2 and now the 1.3 benchmark works. I’ll test shortly with 1.4…

Edit: An Amazon cr1.8xlarge machines gets the following Benchmark, btw, in case anyone’s interested:

BTR Scene 16 passes

yep, that is the usual “windows updates needed” case

Yup, it’s working fine now - how strange! I ran a full Windows update on it earlier :frowning:

Ah well - thanks, Ondra!
