When you click or tap on a certain app inside the Start panel in Windows 10 you might get the message Not installed correctly and the app fails to start.

This error message might occur when you make some changes to the Windows 10 operating system and it affects the registry keys from a specific application.

It can also happen if you have an antivirus that doesn’t let you run an app considering it a threat to the operating system or perhaps the User Account Control feature you have isn’t allowing the application to run,

Usually, by reinstalling the application from Microsoft Store it should fix this issue but if it doesn’t you can follow the instructions posted below and find out some other useful tips.

How can I fix the Not installed correctly error message?

1. Use an antivirus

  1. Disable your current antivirus.
  2. Reboot your Windows 10 operating system.
  3. After the Windows 10 powers up check and see if the antivirus is still disabled.
  4. If it is then you can try and run the application you are having issues with and see if it works

Once your current antivirus has been disabled, your PC won’t be safe, so we recommend you install a trustful and reliable antivirus, such as Bitdefender.
