c# - XAML Designer Window won't load for "Universal Windows" app - even in new project -


i seem recall running before can't life of me recall how got around , no depth of googleing seems help. here's problem:

when open vs2015 (community version) "universal windows" project, new or old, without changing single thing, exception in designer window. xaml code shows fine, designer window gives me

"error 0x80070005: while processing request, system failed register windows.capability extension due following error: access denied."

this followed wall of text i'll include below.

i wonder if due having updated windows 10 (which forced because reason still wouldn't update without common work-around) , adding features vs installation required use universal apps. if open universal windows 8.1 project designer loads fine not universal windows project.

worth noting, i'm amateur learning c#, simple seems bug in ide me...

here's wall of text in case makes sense anyone.

system.exception package not registered.
