Are you joining the conference through your web browser? This sounds like an issue with UAC and Protected Mode on Windows 7. The restrictions imposed by the security features are difficult to explain, so instead I'll link you to a Microsoft article that explains how it all works: http://technet.microsoft.com/en-us/magazine/2007.06.uac.aspx Note that UAC and Protected Mode are both present in Windows Vista and 7, although the implementations differ slightly.How this affects Nefsis: UAC is enabled in Windows 7 by default. UAC allows IE8 to implement Protected Mode (enabled by default). With Protected Mode enabled, IE runs as a process with low privilege. Any application launched by IE inherits this privilege state (this includes Nefsis CC) and runs from a low privilege location on the hard drive which prevents these applications from accessing any higher privilege locations on the system. This would include the desktop, the user profile folder, the program files folder, the root of the C drive, or any external drive. When CC is running in a low privilege state and affected by Protected Mode, you will receive the error you described. If you would like more information on how Nefsis is affected by Protected Mode and UAC in WIndows Vista and 7, please post here or contact our support department.Good catch on the typo in the error message. I was able to verify this exists in the current build and also that it has been fixed in the next release.
