Hello to everyone. I need help or guidance if there are any. I download the starter different versions ( V4.1.1.0 ,  then V5.5.4.9 after failure. None of them work. When I begin installation it stops and displays a message " This program needs SIMATIC STEP7 V5.5.4.9 or higher" Setup terminated.

Is it something I'm doing wrong or trying to get the wrong toll? We have several MM440 VFD, which I would like to connect and commission if needed without using the BOP if possible.

Note: I have Step7 professional 2010 SR1 V5.5+SP1 

 Hello Gandall,

Refer this SIMACTIC STEPS 7 V5.x series for your quick reference.
