  • On Windows 10 x64, after installing Step 7 MicroWIN V4.0 SP9, you will see the error of “pniopcac.exe” every time you restart your computer. How to fix it, please read this post.
  • “@365electricalvn: I found a workaround for this issue. I installed Simatic Manager 5.6 before Micro/Win and after that installation of Micro/Win went perfectly, without any error message. Most probably, Simatic Manager installs PNIO-Adapter (pniopcac.exe) correctly since this is the issue if you try to install only Step7 MicroWin 4.0 with SP9” (Thanks to @guitarguru from Youtube comment).
  • You can try this method on Windows 11, some of our friends tried installing Step7 MicroWIN V4.0 SP9 on Windows 11 and it can be working normally.
See you in the next post. Good luck!
