After installing RAM Structural System x64, the program fails to open. Attempting to open either the desktop or Start menu shortcut for RAM Structural System does nothing.
This is a known issue (TR 4020) that affects only some workstations running a 64-bit operating system. Changes were made in v15.05.00 that should prevent the problem from occurring.
