Hi,
you made sure you started the patch bundle using "Run as Administrator"? I found that this might not be relevant on some installations, but is crucial on others. Something to do with policies. When you reach the cmd part, it's unlikely the InstallShield crashing. Space in your user's local profile is plenty? The IS wrapper extracts everything there, then calls the actual installer through a .bat (which runs from the cmd you see).
HTH,
Andre.
