I have this one W2012 R2 server that will not open any SSIS projects. The server has SQL Server 2014 with the latest version of SQL Data Access tools installed. When I try to open the projects it tells me it is not a support type and if I search for SQL Data Access Tools nothing is found. All my other workstations and servers do not have this issue. I have uninstalled and reinstalled several times now and I have loaded the latest SSDT package. What else can a try to get SSDT to run and open SSIS projects?
