Chaos Browser cannot register the host application

[markus_s_cg]

Chaos Cosmos import in 3dsmax has stopped working. It's downloading and browsing just fine, but when I try to send the asset to 3dsmax 2023 it gives me an error message. The selected importer was not found. (See screenshot).
I've been running the same version for a while, so I don't know what has happened. I tried to reinstall Vray. I'm currently running Vray 5.20.24


Any suggestions how to fix?

Same problem if I try a different Max version (2021)

I don't know. Seems like Cosmos is connecting to the internet and downloading assets. The problem is the connection between Cosmos and 3dsmax. I have found now that it works if I run 3dsmax as admin, but this was not necessary before, and it is inconvenient to do so.

Weird, now it seems like the problem is resolved by itself.
