SSIS script task errors out when executing from SQL Server Agent Job . System.IO.FileNotFoundException: Could not load file or assembly


I have SQL Server 2019 installed on a Windows 2019 Virtual machine. Microsoft Visual studio Professional 2012 is installed on that server.

  • I have bunch of SSIS packages in a project, some of those have script task written in C# 2012 and all those run fine from Visual Studio.

  • Any package which has a script task fails when ran from SQL Server Agent job with following errors.

Description: There was an exception while loading Script Task from XML: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.VisualStudio.Tools.Applications, Version=, Culture=neutral, PublicKeyToken=xxxxxxxxx' 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.

End Error DTExec: The package execution returned DTSER_FAILURE (1). Started: 8:52:01 PM Finished: 8:52:01 PM Elapsed: 0.5 seconds

Some of the thread talked about changing the project property Run64bitruntime to False , didn't work.

Some threads talked about reinstalling SQL Server and Visual Studio but I really don't want to do that as many of those talks about a lot of other errors pops up after reinstalling.

Please suggest what can be done to resolve this.

Translated - DLL of Version of "Microsoft.VisualStudio.Tools.Applications" can not be found.

The message is handy, but it doesn't tell you if the 64/32 bit dll is missing. Some folks take a guess to switch between 32/64 mode and get lucky.

Check your Programs and Featured to confirm "Microsoft Visual Studion Tools for Application 2017" is installed.

Version 14.0 = VSTA 2015

Version 15.0 = VSTA 2017

Version 16.0 = VSTA 2019

Past Version 12, the vsta installer should install dlls for both 32/64 bit support.
