Cannot upload app to Microsoft App Store

Question

Cannot upload app to Microsoft App Store

Mark Johnson 20

I keep getting the error

Package URL should begin with https:// and should point to a versioned, downloadable package.

when I try to upload my msixbundle install file

The url is https://www.mywebsite.com/application/downloads/1.0/applicationinstall.msixbundle

I download the file and install through chrome, so I know it works. Communications on the website are secure with SSL certificate.

Answer 1

The error message you are encountering indicates that the URL you provided for the package must be a versioned, downloadable package that begins with https://. While your URL appears to meet these criteria, there are a few things you can check:

Versioning: Ensure that the URL points to a specific version of your package. The URL should include versioning in the path, such as .../1.0/applicationinstall.msixbundle. Make sure that the version number is consistent with the version you are trying to upload.
Accessibility: Verify that the URL is publicly accessible and that there are no restrictions preventing the Microsoft Store from accessing it. You can test this by trying to access the URL from a different network or using a tool like curl to check the response.
File Type: Ensure that the file at the URL is indeed an .msixbundle and that it is correctly formatted. The Store expects the binary on the package URL to remain unchanged after submission.
SSL Certificate: Since you mentioned that your website uses SSL, ensure that the certificate is valid and correctly configured. You can check this using various online SSL checker tools.

If you have confirmed all of the above and are still experiencing issues, consider updating the package URL in the Partner Center submission to ensure that it reflects the correct and accessible version of your app package.

Hi,

Partner Center is very strict about how the file is served, not just the scheme.

That error usually means one of these:

Redirects or a download page in between The URL must return the .msixbundle file directly on a simple GET.
- No HTML download page
- No 301/302 redirects to another URL
- No login/authentication
Access restrictions The file has to be publicly reachable from the internet (including Microsoft’s servers):
- No IP whitelisting / VPN
- No password protection or cookies
Token/time‑limited links If the URL works only for your session or expires after some time, validation fails.

Quick test

Open a private/incognito browser window.
Paste https://www.mywebsite.com/application/downloads/1.0/applicationinstall.msixbundle.
If it doesn’t immediately start downloading the MSIXBundle and instead shows a page or redirects, Partner Center will reject it.

If you have shell access, also check:


curl -I "https://www.mywebsite.com/application/downloads/1.0/applicationinstall.msixbundle"

You want a direct 200 OK with the file, and no redirects.

If your current hosting adds redirects/pages, host the bundle at a simple, public URL like:

https://www.mywebsite.com/downloads/app/1.0.0/MyApp_1.0.0.msixbundle

and use that in Partner Center.

I ran the following command and it immediately started reading the file.

PS C:\Users\markj> Invoke-WebRequest -uri https://textfileexplorer.com/downloads/1.0.2.0/TextFileExplorer_1.0.2.0_x64.msixbundle

StatusCode : 200

The url still is not accepted by the store

When I try to add the package, I check the msi option, not the exe option. What bothers me is the package is a msixbundle. ?? The other result of trying to submit it is that it unchecks my architecture which is x64.

Again, the error is

Package URL should begin with https:// and should point to a versioned, downloadable package.

Thanks for the details.

Just to confirm, are you submitting this app via the MSIX/Appx flow in Partner Center?

For an MSIXBUNDLE, you need the MSIX/Appx flow where you upload the bundle directly and the Store reads version/architecture from the AppxManifest. I suggest taking a look at this documentation for better details Upload app packages (MSIX)

Do this:

Start a new submission using the MSIX/Appx (Windows app MSIX) path.

Upload the .msixbundle directly.

Verify the AppxManifest Identity version matches and includes x64.

Let me know if this is the case or not, I'll try my best to help.

Yes, I have gone through all the steps of submitting the msix app to the store. They all say Completed. In the partner center settings, I have finished the Payout and tax profiles but can't get by the assignment step.

The Manage payment and tax profiles popup is filled out but the submit button is grayed out. I submitted a bug for this but have not received a response. Others have had the same problem.

Hi, sorry for the late response but has the issue remained the same?

We can’t upload an app to the Microsoft Store if the package isn’t in the correct MSIX/APPX format, the publisher ID doesn’t match, or the app fails Store policy checks. Fixing the package identity, metadata, or certification errors can resolve this issue.
