Corona import

[ALEX_SPYROPOULOS]

Hi all,
I received a corona file from another company, is there any way to convert it to VRAY 6.2 ? When I press convert to Vray I get an error message. Do I need a corona licence? I downloaded an inactivated trial version of corona

This is a *very* old bug in the converter, nothing to do with your actions.
The thing is, in the current V-Ray there is no trace of the bug in the vrutils.ms file.
It would point at some issue with writing rights in the programData folder, or other such reason that left the vrutils.ms file not-updated.
Ensure the file you have is exactly like this one:

If not, uninstall V-Ray, verify the folder's emptied and the file gone, and then reinstall.

let us know if it didn't solve itself.
