The issue may occur because the Script Task is not installed properly. Please check whether the Microsoft.SqlServer.ScriptTask.dll file exists in the following folders (supposing it is a 64-bit platform):

1. C:\Program Files\Microsoft SQL Server\110\DTS\Tasks
2. C:\Program Files (x86)\Microsoft SQL Server\110\DTS\Tasks
3. C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.SqlServer.ScriptTask\v4.0_11.0.0.0__89845dcd8080cc91

If the Microsoft.SqlServer.ScriptTask.dll file is missing in any of the folders, copy one (from the other folders or a different working SSIS server) to the folder. Alternatively, you can also use the command line tool gacutil.exe to install the task assembly into the global assembly cache (GAC).
