We have the SSIS package upgraded from SQL Server 2012 to 2019, they are all working on DEV environment but getting below on QA, I would appreciate for any help on this issue.
The following error(s) occurred:System.IO.FileLoadException: Could not load file or assembly 'Microsoft.SqlServer.ManagedDTS, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies.

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].
