Hello,
The product uses HTML documents served locally. I fixed this error by adding the local domain (Literally 'Local') to the trusted sites list in the Internet Explorer settings.
Add this key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\localhost
Add a "D-Word (32-bit) Value"
Name: http
Value: 1
This works for my installation. All functions work as expected now.
Windows 7 x64, IE9, Novell, ArcGIS Desktop 10, v10.0.4400 (SP5).
I hope this helps.
