If FlyingGrass' method doesn't work, then you can try a method I used!
(I use Windows 10, so if you use another operating system or another version I'm unsure if it works the same, but I'm sure Windows 8 should work the same.)
1. Click on the Windows home button on the bottom left corner;

2. Search 'Uninstall' and this should come up:

"Add or remove programs", then Click it (This program will allow you to uninstall any program you have on your computer)
3. Search for FeralHeart within your list. It should have the icon and the version you're wanting to delete

4. Clicking on it should reveal the options to either 'Modify' or 'Uninstall' the program, click Uninstall

5. After you do this the uninstalling screen/progress bar should show up and will uninstall FeralHeart, it will also notify you when the uninstallation has completed!
(No preview image for this, as I'm not wanting to uninstall my FeralHeart)
I hope this helped! I haven't done a tutorial like this in quite a while so I hope it all makes sense! c:
