I just installed JustDecompile for the first time on my Windows 10 machine, and when I start it up I am getting this error:

Can not load WinRT Metadata, the option is grayed out even though I am running Windows 10 and the C:\Windows\System32\WinMetadata folder does exist.

I also tried open the above folder but JustDecompile says it can not fild the folder! I did start JustDecompile as the admin, no luck.  

Please assist. Thanks. 

whatever exe file or dll file I drag in the justdecompile window, i get a windw with  the error message:

Justdecompile support only valid CLR assemblies. Not supported file:

(name of the file dropped)
