[bedouinbro]

I'm trying to install Dolby Access app from Microsoft Store - Generation Project (v1.2.3) [by @rgadguard & mkuba50] pasting this link provides all the packages Dolby Access - Official app in the Microsoft Store
I am following this guide, Requirements Wiztree and WSAppBak to find the DolbyLaboratories.DolbyAccess_3.22.10269.0_neutral_~_rz1tebttyb220 package and uncompress it and reinstall it from .pfx, .cer, .appx.

App installation failed with error message: error 0x800701C9: While preparing to process the request, the system failed to register the windows.capability extension due to the following error: None of the authorized entity elements in the SCCD matched the app being installed; either the PFNs don't match, or the element's signature hash doesn't validate.. (0x800701c9)

but I'm getting this error, how do I fix it ?

The error message 0x800701C9 you're encountering suggests that there is a problem with the package file not being correctly signed or matching the expected Package Family Name (PFN). This issue most commonly arises due to the signature of the package not being validated against the system's trusted certificates or because of a mismatch in the PFN. Here are some steps you can take to troubleshoot and resolve this issue:

Steps to Resolve Error 0x800701C9​

1. Verify Digital Signatures: Ensure that the digital certificates associated with the .cer, .pfx, and .pvk files are valid and have not expired. You can do this by:
   • Right-clicking on the certificate file (.cer) and selecting Properties.
   • Going to the Digital Signatures tab and verifying the signature details.
   []Match Package Family Name (PFN): Ensure that the PFN in the package you're installing exactly matches the expected PFN. You can verify this by checking the manifest file (AppxManifest.xml) within the .appx package. []Install the Certificate: Make sure the certificate you are using is installed properly to the Trusted People store. Here’s how you can install it:
   • Double-click the .cer file.
   • Click on Install Certificate.
   • Choose Local Machine and proceed.
   • Place the certificate in the Trusted People store.
   []Re-download the Package: There might be a corruption in the existing package files. Try downloading the package again from the Dolby Access - Official app. []Use Powershell: Open PowerShell as an Administrator and run the following commands to install the package:

   powershell Add-AppxPackage -Path "C:\path\to\DolbyLaboratories.DolbyAccess_3.22.10269.0_x64_rz1tebttyb220.appx" -DependencyPath "C:\path\to\dependency1.appx","C:\path\to\dependency2.appx"

   Ensure you replace the paths with the correct paths on your system.
2. Check System Update: Ensure your operating system is fully updated, as certain updates might affect app installations.

   Additional Verification​

   Here are a few more things you can double-check:
   • Ensure Correct File Extensions: Make sure all related files (.appx, .cer, .pfx, and .pvk) are correctly recognized by the system and are not corrupted.
   • Access Rights: Ensure you possess the necessary administrative rights to install the package.
   • Check SCCD: Validate that the System Capability and Configuration Descriptor (SCCD) aligns with the package's capabilities.

   Contact Support​

   If the issue persists, you might need to contact Dolby or Microsoft support for further assistance, given that it might involve intricate details about the package signing and system configuration:
   • Microsoft Support
   • Dolby Support

   Keeping in Mind the Community Guidelines​

   Please remember to avoid posting sensitive personal information online and always respect licensing and usage rights of software packages. Hopefully, these steps will help resolve the installation error. Let me know if you encounter any more issues!
