I'm new to PLC also and I need help installing STEP7 V5.5 SP4. I followed the link above and downloaded the files but I got this error during installation."The software can not be installed on your computer with operating system Windows 8.1 Professional Edition x64" The program sees my operating System as Windows 8 but it is actually Windows 10 Professional 64 bit. Any help would be gladly appreciated.
Thanks in advance,
