Fix Error 0x80073CFB.md

Issue:
Error 0x80073CFB when "Run.bat" is executed to install Windows Subystem for Android (WSA)

Preface:

This issue can arise due to the fact that "the provided package is already installed, and reinstallation of the package was blocked. Check the AppXDeployment-Server event log for details."

Solution

1. Go to %LOCALAPPDATA%/Packages/, and make sure that the folder MicrosoftCorporationII.WindowsSubsystemForAndroid_8wekyb3d8bbwe is deleted. (If it does not exist, move on to Step 2.)

2. Open Powershell (as Admin) and run the following command:

Get-AppxPackage -Name "MicrosoftCorporationII.WindowsSubsystemForAndroid" -AllUsers | Remove-AppxPackage -AllUsers

3. Delete all folders related to WSA (expect the .zip files for WSA Builds), which include folders extracted for WSA installation.

4. Re-extract and re-run Run.bat

The issue should now be fixed
