Running applications with admin rights make applications run with more power. Even if the application fails to open up, try re-installing the application with admin rights. Just right click on the installer file and click on Run as administrator.

2] Download the installer again and then install

Sometimes when you download any application to install, you may have faced a situation where the setup won’t run and the app won’t install. This may happen due to a corrupt or defective installer file. Try downloading the same from the application’s official website or any trusted source.

3] Run SFC scan

Press Win Key + X. A Quick Access Menu will open up.
Click on Windows PowerShell (Admin). If it shows Command Prompt instead of PowerShell then select Command Prompt (Admin).
Run the command: sfc /scannow
Wait for some moments as it takes time to complete the scan.
If everything goes right, the error should get resolved. But, if there is a really big problem then you may encounter a message saying: ‘Windows Resource Protection found corrupt files but was unable to fix’. You just need to restart your machine in Safe Mode and run the above command again.
