I had a look around and found the software WizMouse from Antibody Software. This allows the mouse wheel to be inverted with an option directly in the programme. If you confirm this with OK, the programme goes into the system tray. There is also an option in the programme that if you left-click on the symbol in the system tray, the programme deactivates the functions. The symbol remains active. This means that you can switch the function on and off with a click on the symbol.

THANK YOU VERY MUCH,
I was looking for a programme like this, but unfortunately I didn't find it right away.
Super effort from you !!!!!!!!!!!

Thank you for your answers.
Unfortunately, I am using various CADs where the direction cannot be changed.
If I change it in the WIndows Regedit, they are still in the opposite direction, simply the other way round.
So I would like to set the mouse wheel programme-specifically, so that I can also switch quickly.
Do I have to assume that it doesn't work with the Logitech Options software?

This can be changed with any mouse in Windows with the help of a Regedit entry.
Enclosed are instructions for Windows 7 (also works under Windows 10, tested by myself):

I've had several Logitech mice so far and they all use the same Logitech software and I've never come across such an option. But why do you ask? I know, for example, that there is CAD software in which the zoom function is inverted according to me (for example SolidEdge or Inventor) and you can set this in the software, just as with Google Earth and the like.
