I can't update either. Using the itch app on windows.
I wonder if it's because the file has a different name. Maybe try downloading it from the website.
It works from the website. I tried removing it from the app and redownloading through the app. It works fine that way, too.
Thanks!
Nevermind. Doesn't work on redownload from the app, but website download works.
App says "An error occurred during installation mkdir [directory here]\Itch\slice-dice\jre\lib\images: The system cannot find the path specified."
