Windows & code signing.


Previous versions of LemmingBall Z were digitally signed by me. (Menne Kamminga) Meaning, as long as lbzwin.exe carried that signature, you could be sure it came from me.

Unfortunately this costs money… around 100 to 500 euro’s each year.

This year I decided to stop digitally signing my game, since I lack funds to buy the certificate required.


What this means for you:

  • You may receive a warning from Windows  smartscreen that lbzwin.exe or cb9_1.exe is not trusted.
  • You may need to click “run anyway” in some dialog before LemmingBall Z will run.
  • If you want to be safe, you should download the game only from, not from other sites.
