If you are trying to open a SSIS (.dtproj) with Visual Studio 2012m and you are getting this error message:
This version of Visual Studio does not have the following project types installed or does not support them. You can still open these projects in the version of Visual Studio in which they were originally created.
As you may already know, this means that this project type is not configured on your installation of Visual Studio, but for some installing the support for BI projects is a bit tricky. We can address this by following these steps:
Download the Microsoft SQL Server Data Tools 2012
Run and install the data tools. If this is not installed, the next step will failed to install as well.
Download the Microsoft SQL Server Data Tools – Business Intelligence for Visual Studio 2012
When you run this file, we need to make sure to select perform a new installation of SQL Server 2012. We should note that this option does NOT install a new instance of SQL Server. It only installs the features. We can then select the Data tools feature and complete the installation.
After the installation is complete, all the SSIS project templates should be available on Visual Studio 2012, and the unsupported error should go away.
I hope this helps.
