Export to excel and grid copy on IE 11 fails.

We are using JDE 9.1 and recently upgraded to tool set 9.1.5.10 from 9.1.2. User PC is
Windows 7 (64 bit) with IE 11 (version 86) 32 bit and MS Office 2016. Users are
facing following issues:

1) Export to excel or csv fails. No response is received on
screen and nothing changes on display when either option is selected.

2) Grid copy from excel to forms fail. Only first cell of
first row is copied.

Users got the prompt to enter admin credentials to install
active x files which were provided and active x files duly installed. Those can
be viewed under C:\Windows\Download program files.

We followed all recommendations around active x management,
