The microsoft store doesn't allow me to install an app

Disclaimer: Temporarily turn off antivirus protection. However, keep in mind that if you do so, your device may be vulnerable to threats. So please turn it on immediately once issue fixed. 

Before this, regarding the problem that the Microsoft Store does not have a download button, which may be related to the software damage of the Microsoft Store and the user profile damage, I suggest you try the following scheme: 

First, it is recommended that you check whether your system language, regional and time zone settings are correct, and turn off or disable third-party antivirus software, and then try: 

I. reset the Microsoft Store: 

Press Windows+R→ Enter WSReset.exe

II. reinstall the Microsoft Store 

Run the command in Windows Powershell (Administrator): 

Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"} 

III. restart the MicrosoftStore installation service (solve this case) 

1. Press Win+R to bring up the running dialog box. 

2. Enter services.msc and press Enter. 

3. Find and open the MicrosoftStore installation service. 

4. if the service is already running, click stop > to start restarting it. 

5. Restart the computer and check whether the Install button is now available. 

IV. Reconnect your Microsoft account 

In the Microsoft Store, choose to log out of your current Microsoft account, then press Windows+X, open the Task Manager, close all the progress related to the Microsoft Store, then open the Microsoft Store and log in to your Microsoft account again. 

V. Create a new local administrator account 

Search for CMD, then run in administrator mode and enter the following command 

net user USERNAME PASSWORD /add 

net localgroup administrators USERNAME /add 

USERNAME PASSWORD can be replaced with the account name and PASSWORD you want, and password can be omitted if no password is needed. 

If there is no problem under the new account, it should be a failure of the account configuration file. Please refer to the scheme under repairing the damaged configuration file in the following article to transfer your data to the new account.
