Solution 1: Previous installation is blocking installation

1. Ensure the partition/drive you are installing from is NTFS

2. Redownload WSA Build .zip (sometime the files can be corrupted during download and extraction)

3. Delete all folders containing "WindowsSubsystemForAndroid" in the following directories/paths:

C:\ProgramData\Microsoft\Windows\AppRepository
C:\ProgramData\Microsoft\Windows\WindowsApps
%localappdata\ProgramData\Packages

4. Restart your Computer

Hope this works for you!

Solution 2: Firewall is blocking installation

Windows Firewall

1. Ensure that Windows Firewall is on and is working with "Recommended Settings" being enabled

2. Ensure that Windows Firewall service is running. If not, enable it.

3. Restart your PC

Other Firewalls
