i decided to continue my issue from here
https://forum.corona-renderer.com/index.php?topic=17973.msg125052#msg125052 i hope it is necessary to bump this thread.
hi devs or mike288, yesterday i tried every advises in this thread and nothing changed but after i installed max 2018 idly, surprisingly corona toolbars isnt broken. so, could you please take a time to investigate this helpful-feature issue?
default win program files: c:\Program Files\
max 18: I:\Program Files\Autodesk\3ds Max 2018 -corona toolbar isnt broken.
max 16: I:\Program Files\Autodesk\3ds Max 2016 -corona toolbar is broken.
note: other than corona toolbar is working including corona material library.
