Error Loading Plug-in DLL - Error code 127 - Procedure not found

Note: this error sometimes appears without the "code 127" part!

This error means that there is a DLL version mismatch because either:

  • The current version of Corona does not match the version of 3ds Max where it is installed (example: Corona for 3ds Max 2014 is installed in 3ds Max 2016 application folder)
  • Different versions of Corona are installed in the same folder (example: some files are left from Corona 1.4, and some are from the 1.5 version)


Uninstall Corona (it is avaliable as an item in the Windows "Programs and Features" list). Then install Corona again.
