I solved it this way: I used codex gpt 5.5 to solve it and now chatgpt is working.

ChatGPT/Codex Windows installation hangs before download

Summary

The ChatGPT/Codex Windows app could not be installed through either the Microsoft Store UI, OpenAI's ChatGPT Installer.exe bootstrapper, or WinGet.

The Store UI remained indefinitely at Checking system requirements, while WinGet consistently stopped immediately after accepting the package agreements. No package download or AppX deployment began.

The app was eventually installed successfully by obtaining the current x64 MSIX, verifying its checksum and Windows signature, and installing it directly with Add-AppxPackage. This confirms that the ChatGPT/Codex application package itself is compatible with this computer. The unresolved defect is in the Microsoft Store acquisition path before AppX deployment.

Environment

User-visible behavior

Microsoft Store

  1. Open the ChatGPT product page.
  2. Start installation.
  3. A Store installer window appears.
  4. It remains indefinitely at Checking system requirements.
  5. No download progress appears.

The Microsoft Store Updates and downloads page also remained busy for several minutes without completing.

OpenAI website installer

The downloaded file named similar to ChatGPT Installer.exe did not contain a standalone desktop installer. It launched the Store installer using this URI:

ms-windows-store://pdp/?mode=mini&productid=9PLM9XGG6VKS&cid=website_cta_psi

It therefore encountered the same Store acquisition hang.

WinGet

The following command consistently found the correct product and accepted its agreements, but then stopped making progress:

winget install `
  --id 9PLM9XGG6VKS `
  --source msstore `
  --exact `
  --accept-package-agreements `
  --accept-source-agreements `
  --verbose-logs

The last significant line in every affected WinGet diagnostic log was:

[CLI ] Package agreements accepted by CLI flag

No authentication-broker, downloader, or AppX deployment process started afterward.

The same behavior occurred with:

--disable-interactivity

and later with:

--interactive --authentication-mode interactive

The interactive command did not produce an authentication window. It stalled at the same package-agreement boundary.

Reproduction history

At least four noninteractive WinGet installation attempts were made at approximately:

  • 04:18
  • 04:26
  • 04:39
  • 12:26

An additional interactive installation attempt was made at approximately 18:12. All stopped at the same point before download.

Important diagnostic evidence

Package was not installed

Before applying the workaround:

Get-AppxPackage | Where-Object {
    $_.Name -match 'OpenAI|ChatGPT|Codex'
}

returned no package.

This was not merely a broken Start-menu shortcut or a launch failure. There was no registered ChatGPT/Codex AppX package.

Store product metadata was reachable

WinGet successfully retrieved the product manifest from:

https://storeedgefd.dsx.mp.microsoft.com/v9.0/packageManifests/9PLM9XGG6VKS?Market=US

The response identified:

  • Product name: ChatGPT
  • Publisher: OpenAI
  • Package family: OpenAI.Codex_2p2nqsd0c76g0
  • Supported package architectures: x64 and ARM64
  • Installation scope: user
  • Download prohibited: false

Therefore DNS, general HTTPS connectivity, Store catalog lookup, and product discovery were working.

Clock and network were valid

The local UTC time differed from the Microsoft HTTP server's Date header by only a few seconds.

No WinHTTP proxy, user proxy, or Store-disabling group policy was configured.

Dependencies were healthy

The Store, Desktop App Installer, Windows App Runtime, VCLibs, and UI XAML packages all reported Status: Ok.

The following services were available and could be started:

  • AppXSvc
  • ClipSVC
  • InstallService
  • TokenBroker
  • wlidsvc
  • wuauserv

Store event-log errors

The Microsoft-Windows-Store/Operational log included this unhandled exception:

App.UnhandledException: "The message filter indicated that the application is busy.

A COM call (IID: {727D1449-1A71-5A00-8746-E4A1C8CAAEE1}, method index: 3)
to an ASTA appears deadlocked and was timed out."

Exception Details: System.Runtime.InteropServices.COMException

The same log also contained:

Corrupted PersistentPerUserCache index, creating a new one (userId = "0").
Error Code: 0x80000000

and:

Task 'WinStore.Tasks.StoreAppServiceTask+Runner' was canceled,
reason: 'SystemPolicy'.

The Store installer successfully reached these stages:

  • Started the Store SFEdge call
  • Detected native OS architecture as x64
  • Confirmed allowed architectures x64 and ARM64
  • Previewed and decoded the product license
  • Confirmed the age-rating check

It did not proceed to package download or AppX deployment.

WinGet download authentication error

A separate winget download test returned:

Authentication failed. Interactive authentication required.
Error code: 0x8A150076
Failed to authenticate for MicrosoftEntraId

However, forcing interactive authentication during winget install did not display an authentication prompt and still stalled immediately after package-agreement acceptance.

No ChatGPT deployment failure was recorded

There was no corresponding ChatGPT/OpenAI failure in Microsoft-Windows-AppXDeploymentServer/Operational because the Store acquisition client never handed a package to AppX deployment.

This distinction is important: installation did not fail while registering or deploying the MSIX. It failed before the MSIX was downloaded.

Troubleshooting attempted without success

The following did not resolve the Store acquisition problem:

  1. Microsoft Store Repair.
  2. Microsoft Store Reset.
  3. Restarting Windows.
  4. Retrying the Store product page.
  5. Retrying the OpenAI Store bootstrapper.
  6. Repeated noninteractive WinGet installation attempts.
  7. WinGet with forced interactive authentication.
  8. Verifying disk capacity, Windows version, architecture, region, clock, network, and proxy configuration.
  9. Starting the Microsoft account, licensing, update, and AppX services.
  10. Re-registering these existing signed packages:
Add-AppxPackage -DisableDevelopmentMode -Register `
  "C:\Program Files\WindowsApps\Microsoft.StorePurchaseApp_22605.1401.3.0_x64__8wekyb3d8bbwe\AppxManifest.xml"

Add-AppxPackage -DisableDevelopmentMode -Register `
  "C:\Program Files\WindowsApps\Microsoft.WindowsStore_22605.1401.13.0_x64__8wekyb3d8bbwe\AppxManifest.xml"

Add-AppxPackage -DisableDevelopmentMode -Register `
  "C:\Program Files\WindowsApps\Microsoft.DesktopAppInstaller_1.29.280.0_x64__8wekyb3d8bbwe\AppxManifest.xml"

All three packages re-registered successfully and reported Status: Ok, but the ChatGPT WinGet installation still stalled at the same point.

Workaround that succeeded

Because the Store acquisition client remained blocked, the latest x64 MSIX was obtained through the unofficial Wangnov/codex-app-mirror GitHub release. That project states that it resolves the Windows package from Microsoft Store metadata and mirrors the resulting package without modification.

The specific package installed was:

OpenAI.Codex_26.707.3748.0_x64__2p2nqsd0c76g0.Msix

Verification before installation

The downloaded package was not installed blindly. It passed all of these checks:

Expected SHA-256:
181faac13711ed38213c38644be2fc176f78f65a057cd167dc044935d3e81ab9

Actual SHA-256:
181faac13711ed38213c38644be2fc176f78f65a057cd167dc044935d3e81ab9

Checksum match: True
Authenticode status: Valid
Identity name: OpenAI.Codex
Version: 26.707.3748.0
Architecture: x64
Target family: Windows.Desktop
Minimum Windows version: 10.0.19041.0
Package publisher: matched the valid embedded signer identity

The computer runs Windows build 19045, which exceeds the package minimum of 19041.

Direct installation command

Add-AppxPackage `
  -Path ".\OpenAI.Codex_26.707.3748.0_x64__2p2nqsd0c76g0.Msix" `
  -ForceApplicationShutdown

This completed successfully in approximately one minute.

Post-installation result

Name: OpenAI.Codex
PackageFullName: OpenAI.Codex_26.707.3748.0_x64__2p2nqsd0c76g0
PackageFamilyName: OpenAI.Codex_2p2nqsd0c76g0
Version: 26.707.3748.0
Architecture: x64
Status: Ok
Start-menu name: ChatGPT
App ID: OpenAI.Codex_2p2nqsd0c76g0!App

Launching the registered application produced:

  • A visible top-level window titled ChatGPT
  • Responsive ChatGPT main, renderer, GPU, storage, and network processes
  • Successful AppModel activation event
  • Successful TWinUI activation event with result 0

This proves that the MSIX package, application runtime, Windows build, GPU process, and application registration all work on the affected computer.

Confirmed conclusion

The application package itself is not the blocker. The failure occurs in the Microsoft Store/WinGet acquisition path after product discovery and agreement acceptance but before package download and AppX deployment.

The Store event log strongly suggests a Store client COM/ASTA deadlock or related per-user Store acquisition-state failure. The exact internal cause cannot be proven from public logs alone.

The direct MSIX workaround resolves installation but does not repair the underlying Microsoft Store acquisition defect.

Requested maintainer investigation

Please investigate:

  1. Why the Store installer can complete compatibility and license preview but never initiate download.
  2. Why WinGet blocks after Package agreements accepted by CLI flag without an error or timeout.
  3. Why --authentication-mode interactive does not open an authentication broker when Store acquisition requires it.
  4. Whether the Store ASTA appears deadlocked and was timed out COM exception is related to the stalled acquisition.
  5. Whether ChatGPT/Codex can provide an official direct Windows MSIX or standalone installer for systems where Microsoft Store acquisition is broken.

  • OpenAI Codex repository: https://github.com/openai/codex
  • Unofficial workaround mirror used: https://github.com/Wangnov/codex-app-mirror

Security note

The successful workaround used an unofficial mirror only because every official Store acquisition route was blocked. The package was accepted only after its release checksum matched, its Windows Authenticode signature validated, its manifest identity matched the Store package family, and its Windows/architecture requirements were inspected.

An official OpenAI-hosted Windows installer would be preferable.
