Patching (Store Licensing Bypass)

If the app fails to launch with this error in Event Viewer (Microsoft-Windows-TWinUI/Operational):

Activation failed. Error: The network location cannot be reached.
Activation phase: PLM prepare for activation

This means Windows can't verify the Store license. The fix is to re-sign the package with a developer certificate.

Prerequisites

• Windows SDK - for makeappx.exe and signtool.exe
• Developer Mode - Settings > Privacy & Security > For Developers
• Run as Administrator - for certificate installation

Patch & Install

# Run as Administrator
.\Patch-3DBuilder.ps1

# Remove Store-signed version
Get-AppxPackage -Name '*3DBuilder*' | Remove-AppxPackage

# Install patched version
Add-AppxPackage '.\3DBuilder-20.0.4.0-Patched.appx'

What the Patch Does

Before	After
Name="Microsoft.3DBuilder"	Name="Local.3DBuilder"
Publisher="CN=Microsoft Corporation..."	Publisher="CN=Local3DBuilder"
SignatureKind: Store	SignatureKind: Developer

The patched app bypasses Store license verification entirely.
