Package migration from version 8 to version 6 failed with error 0xC001700A

Question

SSIS package built in VS 2013 (v 12.0.31101)
DTSExec run on SQL Server 2014

Description: Package migration from version 8 to version 6 failed with error 0xC001700A "The version number in the package is not valid. The version number cannot be greater than current version number.".

I see lots of google results for the above when people use SQL 2012, but I am on 2014 and can find no support. The versions should match (i.e. both be package version 8)

select @@version

Microsoft SQL Server 2014 (RTM-CU14) (KB3158271) - 12.0.2569.0 (X64) May 27 2016 15:06:08 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 6.3 (Build 9600: )

Additional info - looks like it is running an older DTSExec, pehaps from a now deleted instance of sql 2012. How would I fix/repoint to 2014?

Solution

Found that I could force it to use the correct dtexec as follows:

Go to PATH environmental variable and edit it in such a way that "C:\Program Files\Microsoft SQL Server\110\DTS\Binn" path appears well before the "C:\Program Files\Microsoft SQL Server\100\DTS\Binn" path.

Followed by restarting the SQL Server service. Now it shows correct version:
