Summary
You are required to restart the IE when the browser is open while you are upgrading older versions of WFBS Security Server to the latest version.
Details
This issue happens because old ActiveX controls are loaded during the upgrade. This means refreshing the new ActiveX controls is required.
As a workaround:
- For Internet Explorer (IE) 6 and below, restart IE.
- For Internet Explorer (IE) 7 and above, clear the cache and restart IE. If you need more help with clearing IE cache, refer to the Microsoft article: How to Delete the Contents of the Temporary Internet Files Folder
