Actually - there is a whole stinkpile of CCP files that are listed as problems when the installation fails:
This message also appeared:
Return code: 0x80004005
Description: Unspecified error
XML Parser error: The node is neither valid nor invalid because no DTD/Schema declaration was found.
The Function also changes with the file. I have permitted all versions of TLS and SSL. I would normallly reinstall TCP/IP at this point, but that is not an option on Windows 7. Could this be an anyconnect version issue since it appears to be the only affected application?
I'm totally flummoxed.
UPDATE: Also looked up the file type and noticed that it's a C++ pre-processor file... and that .NET was also updated in the recent SLEW of Windows updates. Could this be a .NET issue instead of a BITS issue?
