When trying to install a program or app in Microsoft Windows 10, I receive the following error message:

Your PC's settings only let it install verified apps from the store

There are two reasons that you may not be able to install Apps on your Windows 10 Computer:

• In Windows settings the Installing Apps switch is set to Allow apps form the Store only
• Windows 10 in S mode is designed for security and performance, exclusively running apps from the Microsoft Store.

Before assuming that Windows 10 is in "S" mode confirm that Windows Settings are set to allow apps from Anywhere,  Perform the following steps first: 

1. Click on the Start Menu 
2. Select Settings 
3. Select Apps
   
   
    
4. Select Apps and Features 
5. From the Installing Apps dropdown you have 3 Choices
   • Allow apps from anywhere
   • Warn me before installing apps from outside the Store
   • Allow apps from the Store only
6. Choose the one best suited for your needs. If you select Warn me you will get a dialog box that will ask if you are sure you want to install
7. If that fixes the issue you are done, If you do not have those settings or they are grayed out continue to the next section

To allow the download and install of app on a Windows 10 machine, see the following Microsoft article:  

Switching out of S mode in Windows 10

Note per the article: If you make the switch, you won't be able to go back to Windows 10 in S mode. There's no charge to switch out of S mode. If you have questions on the impact, it is recommended you contact Microsoft Support.
