You mean a desktop app that you need to download, install, and during the installation potentially give some privileges that can harm your computer.. then you are trying to install and it doesn't have the right dependency so it asks you to find some random thing to get it working. Then you do get it installed, but don't know where it installed to so you have to go searching for it. Then you get it up and running and it works fine. You play with it for 5 min. 2 months later you come back to it and want the newest version, so you have to download an update, because the auto-update feature was blocked by your firewall. Then you get it updated and running. A couple days later you decide not to use it, so you go to uninstall it. The uninstaller fails for who the f knows why so you delete the folder on your drive, but your OS still think it's installed. So you figure out how to manually remove it.
