Thank you so much for your replies! Yes it seems they deleted the firmware update. I actually managed to install the update though. When I searced and searched for it I found a site with links to the update, but it also said that if the links didn't work, to copy the adress and go to web.archives.org, so when I entered the copied Web adress there I got two dates in a calender, one in 2015 so I clicked and there the zipfile was!
After installing the update I successfully installed chdk! 🙌😊
I will contact canon though and see if it is an error on there part that the firmware update is not there, or if they stopped supporting it.I really hope its a mistake, otherwise I will be disappointed in canon.
I recently bought a nikon coolpix 5400 from 2003 and there was no problem finding the firmware update for this camera on there site (the update enabled raw shooting on it)
