It's impossible to say if the application is compatible with Windows 10 or not, because no system requirements are provided on the official website. I have checked all the pages, but nothing could be found. You can install it in Compatibility mode if you please, but that doesn't guarantee it will work.
However, I advise using CCLeaner instead of Error End, due to its popularity and safe information provided. Customers have been complaining about Error End being a scam.
