call RequestPurchaseAsync fail

Question

call RequestPurchaseAsync fail

华张 156

My app needs to call Microsoft Store to pay, and following:

Get all add-ons, it's work good.
Select one add-on from step 1 called RequestPurchaseAsync API.

The normal situation is to pop up the Microsoft login page, and then select the payment method

But in step 2, the Microsoft login page disappeared very quickly when I call RequestPurchaseAsync API, look likes an exception or inner error

this is an error because of MS no correct response(pop up a login page).

Not all device isn't working, some of them can do it.

What should I do?

Could you please tell me the OS version of these not working devices? And what's the target version of your app? This RequestPurchaseAsync API will launch the Authentication process to purchase. And it is under the control of the system. It's like what you've done in the Store.

Hello,

Welcome to Microsoft Q&A!

I discussed your issue with other engineers. The issue needs more professional support and it might require some device log which is not suitable to show in the forum. I suggest that you might need to open a support ticket for this. Please contact our paid phone support at MS Support. You will get 1:1 support on that. Please kindly note that your support ticket will be free if it is Microsoft's issue. Choose Developer tools-> Windows UWP Development-> Windows 10 Universal App Dev and pick the topic you want to ask.

Thank you.

I think this problem may be caused by administrator privileges, because the computers that cannot be displayed normally are administrator privileges accounts, and they are all domain accounts of the company

You could try it with a normal account that does not belong to the company domain in a normal network.

EnablueLUA = 0 : Microsoft login page disappeared very quickly when call RequestPurchaseAsync API

EnablueLUA = 1 : RequestPurchaseAsync API works normally

This is the result of my testing.

It seems that the related issue occurs when the EnablueLUA registry value is set to 0 and used.

Many users set this value to 0 to use Windows without restrictions with administrator rights...
