Using IE11 with ZENON 6.51 web client

Using IE11 with ZENON 6.51 web client

Hello,
On our plant is installed a Zenon web server with 25 view only web clients.
On all Windows 7 computers, IE11 is installed.
On few of those computers when VBA is activated an error occured at activeX startup and ZENON client will not start.
On other computers the web client starts. But on few objects a VBA script is used and will launch a simple MsgBox but when I try to launch this script, MsgBox doesn't appear.
So I have done this chek :
- Opened the VBA editor on those computers
- Activated the breakpoint before the MsgBox line
- Launched the script
- Do "F8" to see the activated yellow line
When MsgBox line is activated the MsgBox window will not appears and no debug error will appears.
So I have two questions :
- How do I configure IE11 to enable VBA on Web clients ?
- Why MsgBox will not appears ?
Best regards,
Emmanuel
