Apps won't install in Microsoft Store

Hi,



Thank you for writing to Microsoft Community Forums.



We understand your concern as you are unable to install apps in Microsoft Store. In order to get clarity and to assist you accordingly, please reply with the answers
to the questions below:

• 
  Do you have any non-Microsoft antivirus program installed?
  
• 
  Does this issue occur for all apps from the store?
  
• What is the date and time on the PC and ensure it is correct?

Meanwhile,
we would suggest you to perform these steps and after every step check if you are able to install the app.



Step
1: Reset the Windows Store Cache: Press the Windows
Logo Key + R to open the Run
dialog box, type wsreset.exe, and then select OK.



Note:
A blank Command Prompt window will open, and after about ten seconds the window will close and Microsoft Store will open automatically.



Step 2: Run the Windows Store Apps Troubleshooter: Select the
Start button, and then select Settings>Update & Security
> Troubleshoot, and then from the list select Windows
Store apps > Run the troubleshooter.



Step 3:
Refer the troubleshooting steps and mentioned

Step 4: If you have any non-Microsoft security/antivirus software installed, disable it temporarily and
then try installing the game.



Step 5: If the issue persists, then we would suggest you to create a new administrator user account and
check, refer this article to create
a local user or administrator account in Windows 10.
