It's about the game: Pumuckl - Catch the Klabauter, dating back to 1995.
Where can I download the game?
And more importantly, what program do I need to play the game on my Windows 10 notebook?
Look at http://www.goldesel.to there are a lot of old and new PC games for free but just illegal.
On pages like https://www.myabandonware.com/
or http://www.abandonia.com/de
you can download many old games. Many of them are DOS games that do not run on a modern Windows. You can do this with a dos emulator like https://www.dosbox.com/
there, under comments, someone is looking for DL, and there in the commentary is the link.
yes the old dos games only under dos-box.oder virtual operating system created.
