If I have VS 2015, should I be able to create a package using DFT+ with TargetServerVersion SQL 2014?
I had a package I created in VS 2013 and deployed to SQL 2014. Now I have VS 2015.
I can only make changes if I set TargetServerVersion to SQL 2016, but then I'm unable to deploy to SQL 2014 (I can deploy, but can't run; I get the following errors)
Error: Failed to load task "DFT+ Create Data File

If I change TargetServerVersion to SQL 2014, I can no longer modify DFT+.

I'm not sure if this should be possible, or if I am doing something wrong, or installation problem maybe, or something else.
Thanks,
Martin
