How to change a script task version in SSIS?

I believe I have the same issue, and here is the work around that got over my issue.

Details first:

• I have sql server 2016 (13.0.4411.0)
• SSISDB has the schema version (13.0.1601.5)
• I am using an integration services package created in visual studio
• The script component (Which states it is 2015 C#) has the path: C:\Program Files (x86)\Microsoft SQL Server\130\DTS\Binn\VSTA14_IS_ST_CS_Template.vstax

If I deploy to the catalog through SSMS, it won't let me execute the package through the integration services catalog (due to the message experienced by Zach - version 15.0 not supported).

The workaround:

If I deploy the package through Visual Studio to the 'Integration Services Catalog' on the required instance, this message goes away and the project runs successfully. This is not ideal as we should be able to deploy through SSMS, but meant that the project can progress.

My DBA finally figured this out for me and the issue was that I was deploying through SSMS 2017 without realizing it. The error message led me astray but your workaround helped lead to the reasoning behind the failure. I guess you can try SSMS 2016 and see if that works. The other way that my DBA suggested is to use the command line. Something like this, with 130 highlighted since that is the version you need for 2016:

"C:\Program Files (x86)\Microsoft SQL Server\130\DTS\Binn\ISDeploymentWizard.exe" 
/Silent /ModelType:Project 
/SourcePath:"E:\ssis\Project Path\bin\Development\Project.ispac" 
/DestinationServer:"server01" 
/DestinationPath:"/SSISDB/Projects/Project"

I hope that helps clear this up. I worked on it for a long, long time before finding your workaround and then finally finding this solution. So thanks!
