I installed this game via the itch.io app and the only compressed file I could find was a gz(ip) file with the file manifest in it having gotten this error (except that only the C++ Runtime was missing) - I'm not surprised as I have DirectX installed and given the dozens of games I have played on this machine I also have just shy of a dozen MS Visual C++ runtimes installed so either your one is very old (I've everything more recent, 32 and 64-bit) or the ones already installed are not being checked... this is an issue because there is a limit to the number of times I want this single library installed, thank you (especially since nothing is kind enough to uninstall it once they are done with it :( - least of all MS :( :(
As a quick fix I would recommend is downloading the game from the site instead than using the app! If you do that you should find a folder that, once unzipped, presents the .exe and 2 folders (picture below):
In the meantime me and one of the progs are trying to wrap our head around what happens when using the itch.io app- it's the first time we're hearing of something like this, so we're sorry for the inconvenience!
No problem, thank you for the workaround and apologies... it seems that the app is not so popular though it is pretty useful for my gaming needs! (I guess a lot of devs might not find it so useful? But for me it is a better version of Steam! :D - faster, simpler and with a better selection of good games ;)
Thank you again and once I've given the game a fair try I'll leave a review :)
