I CANT RUN THE PATCH I DOWNLOADED IT AND IT SAID SOMETHING WAS MISSING FROM MY COMPUTER SO IT CANT BE RUN HELP PLEAAAAAASE
I know Ame has said what I'll essentially run down as well- but I'm not sure how familiar you are with locating all of this so for peace of mind here's a very brief step-by-step look into it. Files > Local Disk (C:) > FeralHeart This is where you can find the FH folder, unless you put it somewhere else (which most don't do).
FeralHeart.com > Download> FeralHeart executable (1.17a) Right click the FeralHeart executable and select 'save link as' to keep it. I highly recommend simply saving it to your desktop for easy access.
FeralHeart.exe (on your desktop) > Local Disk (C:) > FeralHeart (Folder) Drop the downloaded .exe for FeralHeart into the main folder, using the steps above if needed. Then, select "replace all files in destination" (or whichever replace message appears), allow it to load and you should be able to open the game properly!
If you're still having issues, could you specify what error message your PC was giving you? There might be a solution from there.
