Update

• On Windows 10 x64, after installing Step 7 MicroWIN V4.0 SP9, you will see the error “pniopcac.exe” every time you restart your computer. How to fix it, please read this post.
• When you download the program to PLC S7-200, may see an error “A compile error occurred, check non-fatal errors for more information“. Refer to fix it in my Video Area (V0003).
• “@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 work normally (Refer to it in my Video Area (V0006).
