SSIS GAS on SQL2012 with OS 2012R2 problems

Jun 6, 2014 at 12:08 PM
I installed the tool on a system using SSDT2010 and SQL2012 on a OS 2012R2.
The problem is the dataflowtask can not be opened to modify, only by editing the properties of the task it is possible to let it work. The task is also not visible un the SSIS toolbox (common) like in my other installation. the only difference is the OS (2008R2)
Suggestions ?
