Issue Installing .apk file

Question

I have a problem while I'm installing my app. I had made an process that checks if exists the new version of the app. My app is private so I uploaded the .apk file to my private server. And when I download the app and I install it at the end shows me an error "Application not installed". Anyone had a similar problem?
