I was unable to upload Keep AttributesHorizontal.dll in AutoCAD and have got the error message below. I pressed F2 in AutoCAD to be able to read the error message. Please give some advice. Thank you very much for your time!

WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
