I am having problems too, i clicked on Install and it created a folder and seems to have unpacked all the files there but no launch option on Itch. Going directly to the folder and tried to launch and got error "The file or directory is corrupted and unreadable". I also tried to set it to run typewriters or winsetup.ext as Windows Vista Service Pack 2, but that didnt do anything. The instructions was to unzip, but there is nothing to unzip. There are 7 files.
Update: looking at the downloads section of Itch app, it says An error occured during installation zip: unsupported compression algorithm.
Why doesnt this game have a proper installer?
