Any help on this issue ?
Sorry for the delay! Next time please remember that you can contact us here -
https://coronarenderer.freshdesk.com/support/tickets/newSupport is the more "official" communication channel compared to the forum.
Try this:
Go to your 3ds Max installation directory (e.g. C:\Program Files\Autodesk\3ds Max 2020).
Use the Windows search feature.
Enter the following one by one and search for those files:
Legion*
Corona*
ScatterCore*
If anything is found - remove those files. Remember it is best to move files to trash bin instead of removing them completely, so that you can restore them if needed.
Once the cleaning is done (i.e. after you have removed all of the above files from your 3ds Max folder), try installing the newest version again.
If that does not seem to help, please contact us using the link I shared above and if needed we will have a Team Viewer session.
