note:  1 wierd thing happening. if rdc(remote desktop client) box( not working) different computer works fine. not sure how rdc differetn computer make difference?

hi,

your clients need install latest versions of silverlight (32 , 64bit versions),

and

you need update html application use latest version of silverlight.js or use static object tags display silverlight content.

or

if client has installed enterprise site mode lists, add site list , use enterprise mode. (aka ie8 emulation). depending on seats @ clients' office , number of intranet sites managing, should have deployed enterprise site mode lists ie11 on win7-10.
