How to install SSIS on SQL Server 2014?

The SSIS intallation is working as a charm, the only problem was that we wanted to connect to SSIS 2014 from SSMS 2012.

At the end we agreed to upgrade the developers machines to sql server 2014 developer edition, and migrated the packages to sql 2014, and now everything is working fine.

I will leave the question here as a reference, for the community and for myself, because at the end I had so many problems, and they all have been solved.

You can use below steps as mentioned on MSDN :

• Component Services -> Computers -> My Computer -> DCOM Config -> MSDTSServer
• Right click on MSDTSServer
• Click properties
• Click on the Security tab
• Select Customize and add the users/groups to the Launch/Activation and Access tabs accordingly
• Add the user to the local Distributed COM Users group
• Restart the SSIS service

Also, would suggest you to go through the tip How to resolve SSIS access denied error in SQL Server Management Studio which has helped us as well.
