A project containing a System Generator design is opened in Project Navigator on a Windows Vista machine. However, when running processes such as simulation, synthesis, and implementation, the process appears to start but then returns without any action.
System Generator is not supported on Windows Vista and as such, should not have been allowed in the Project Navigator design on this operating system. The incorrect allowance leads to processes that appear to do nothing, since Project Navigator does not know what to do with a module that has no available application to process it.
This problem has been fixed in the latest 10.1 Service Pack available at:
The first service pack containing the fix is 10.1 Service Pack 2.
