Title: NVIDIA Missing DLL
Post by: johnnyswedish on 2023-11-06, 18:59:28

Hi Support,

Since upgrading to the latest 11 version, I'm getting this error (sure a lot of people are). I have a Gforce RTX2080 Studio card in my laptop with 64GB ram & Windows 11 Pro. All Nvidia drivers are up-to-date. How do I make this annoying message go away every time I use IR rendering? Looked at the link but still a bit baffled, thanks, John :-)

Hi,

Tried a clean install, no apps open. Still get the warning. Only got this from the last update. Not a emergency, only comes up during IR rendering but annoying when you have loads of windows open :-)

I tried those remedies too, to no avail. Did you check if the dll file does actually exist on your system and where it is located?  In Windows it should be located C:\Program Files\Corona\optix\cudart64_110.dll. For me it seemed the Corona installer was creating a new optix folder containing cudart_110.dll and placed it in the old optix floder. So my system file structure was  C:\Program Files\Corona\optix\optix\cudart64_110.dll. Once I moved the dll into the top optix folder and deleted the subfolder the constant error message went away.
