Follow the prompts that will come up during the installation to conclude the installation process

When the installation has been concluded successfully you will find Step7 MicroWin V4.0 SP8 or SP9 in your start menu under the item Simatic

After the installation please delete the temporary sub-directory with the installation files manually

If you do not have an existing version of Step7 MicroWin V4.0:

You will need to obtain a valid license for Step7 MicroWin V4.0 from Siemens Industry Mall[^2^] or your nearest Siemens rep.

You will also need to copy the file microwin.exe from another computer with an executable predecessor version of Step7 MicroWin V4.0

You can find this file in drive C in the folder: Program Files\\Simatic\\STEP 7-MicroWIN V4\\bin

Paste this file on your new computer

Troubleshooting tips

If you encounter any problems during or after the installation, here are some tips that might help:

Make sure you have administrator rights on your computer

Disable any antivirus or firewall software that might interfere with the installation

Check if your operating system is compatible with the service pack you are installing

If you are using Windows 10, you might need to install Step 7 v5.6 SP2 first to enable the drivers for connecting to a S7-200 CPU[^3^]
