Missing dlls

Hello! I’ve just installed 3DS Max, then Corona as well (tried the latest and also the 2018).
When I open a file in 3DS Max, I get an error message about missing dlls:

coronautils2018.dlt Class: CoronaMtl
coronautils2018.dlt Class: CoronaFrontBack
corona2018.dlr Class: CoronaRenderer

Can anyone help in this? The textures are not visible.

In what version of Corona was the scene originally saved, and what version did you install?

The best idea is to install the newest one (V6): Download | My Chaos

If it doesn’t seem to help, please try installing Corona manually as instructed here:

It was saved in Corona V3 (2018).
So I tried to install V3 first, then V5 as well.
V5 already promised that it works with 3DS Max 2021 (this 3DS Max has only free trial, as I saw).
But I got the same error message.

I give a try to V6, then I will try to install manually.
Thank you!

Thank you! I could install manually, it solved the missing dll issue (the missing textures issue still exist).
