here now, i get error when try to install plcsim.

Software version: s7 v.5.6
PLC sim v.5.4
Windows 7 Professional SP1 64bit.

Maybe because i install PLC sim separetly?
First, i install s7 v.5.6 after finish the instalation and restart the computer, then i install plcsim. Maybe because of that?

I already follow your video, and get error when download the program, error said:" cannot load the selected communication driver. File not found"
I think, as a manual book said, the CPU is not accessible

Based on manual book, the CPU doesn't support with the PG/PC interface. Maybe there is anybody can help me.
Thank a lot.

i already connect to the MPI, but still same problem.
Maybe because i install the PLCSIM separately?

Maybe have a problem with my PLCSIM, because at the communication interface, text show not BOLD.
Here i attach screenshoot.
