Help File Access

[Roger]

When trying to access the help file, I get the following error: Internet
Explorer Script Error; An error has occurred in the script on this page;
Line: 5, Char: 1; Error: Object doesn't suppor this property or method; Code:
0; URL:
mkMSITStore:C:\Program%20Files\Microsoft%20Office\Visio10\1033\Help\Visio.chm::/VM_Main_Help_Topic1.htm.

Windows 2000 - all the latest updates, IE6

Have uninstalled, reinstalled, no help. Any help appreciated.

Thanks,
Roger
