I have recently installed step7 microwin v4.0 and wincc flexible 2008, and my project is based on them. I am using s7-200(cpu226). these softwares were working properly but i had to exchange the tags between miocrowin and wincc so i installed opc server (PC access v1.0) and after installing it i am getting an error for Unlicense version. I have tried re-installing the Automation License Manager and even re-installed the whole software(wincc) after cleaning the registry but still I am getting this error. Please can anyone help me?
Thank you.
