Brokered UWP Component - Administrator privilege

I am trying to use a 3rd party API to print an html file. When I use vendor's SDK in WinForm application, it fails during InternetExplorer operations. (error is below) So I found out that process should run only on "Administrator" privilege. And then, application and print operations work well.

The object invoked has disconnected from its clients. (Exception from HRESULT: 0x80010108 (RPC_E_DISCONNECTED)): Stack Trace: at System.Runtime.InteropServices.ComTypes.IConnectionPoint.Unadvise(Int32 dwCookie) at SHDocVw.DWebBrowserEvents2_EventProvider.remove_TitleChange(DWebBrowserEvents2_TitleChangeEventHandler ) at SHDocVw.InternetExplorerClass.remove_TitleChange(DWebBrowserEvents2_TitleChangeEventHandler )

My question starts after that. I have to use same API to print in a brokered UWP app. Say it is a assigned-access / kiosk application. I know UWP cannot run with user elevation, but i assume brokered app should have some settings to run, basically "dllhost.exe" as administrator. Because of the application should run on assigned access mode, I cannot set assigned access user as Administrator. (I have doubt it will work even if i set it)

Are there any possibility to run dllhost.exe as admin? Or any other suggestion for issue?

If compared with WinForms framework, UWP has significantly different security model. Same issue for the list of APIs available, and for app-level lifetime schema. Thus, I would suspect you have to contact your vendor for UWP-compatible SDK.
