Can't reinstall Arduino

So I'm a total noob at Arduino, but something didn't seem to work. So I tried uninstalling Arduino by deleting all it's files and then I tried a reinstall, but it keeps saying that it's already installed and that I need to uninstall the thing.

Can someone help me?

I had the same thing. You can download the standalone version and extract to the directory were your previous installation was.

You need to “uninstall” it using the programs and features control panel.

You should never remove any program that had an “installer” by just deleting it’s files - you need to uninstall it using the uninstaller (via the control panel), and then you can delete any leftover files. After doing that, you’ll be able to reinstall normally.

Clean up instructions attached.
