Can't download KaM remake
a friend of mine had an outdated version of KaM so he tried to download the never version, upon starting the update installer, it told him that he doesn't have the original KaM installed on his computer, which is not true. He can even play the original KaM so it's not damaged.
I posted a few attachments with pictures related to this problem, it shows the error and the file location of the original KaM
Could somebody please help him with this? KaM is one of his favourite games and he really wants to play it again.
