Partner Center Support Request Creation Fails – Need Help Migrating Existing EXE/MSI App to MSIX

Hello,

I am an individual Windows app developer. I need assistance with changing the package type of my existing Microsoft Store application from EXE/MSI to MSIX.

1. Current App Information

• App Name: PhonePC

Current Package Type: EXE/MSI

Desired Package Type: MSIX

2. Package Conversion Request

I originally published my application, PhonePC, using an EXE/MSI installer.

I would now like to distribute the application as an MSIX package.

My goal is to retain:

The existing app name: PhonePC

The existing brand identity

The existing Microsoft Store listing and Store ID, if possible

Existing users and app recognition

I understand that Microsoft Store may not support directly changing the package type of an existing product.

If direct conversion is not possible, I would like to know whether Microsoft can help migrate the existing app name and Store listing to a new MSIX product.

I would prefer not to create two separate Store listings for the same application.

3. Partner Center Support Request Error

I have tried to contact Microsoft Support through the Partner Center dashboard.

However, every time I submit a support request, I receive the following error:

"There was a problem creating your service request. Please wait 10 minutes and try again."

I have attempted to submit the request approximately 10 times, but the same error persists.

As a result, I cannot contact the appropriate Microsoft support team through Partner Center.

4. Questions

Is it possible to convert an existing EXE/MSI Store app to MSIX while keeping the same Store ID?

If direct conversion is not possible, can I publish a new MSIX product using the existing app name, PhonePC?

Can Microsoft help migrate the existing Store listing or resolve potential app name conflicts?

Is there an alternative way to contact Microsoft Store support when the Partner Center support request system is not working?

I would appreciate guidance on the recommended migration process and how to resolve the support request submission error.

Thank you for your help.Hello,
