Hi Barry,
Thanks for the suggestions. I checked the logs for the packages but couldn't find a "value 3" message in them. Uploaded the log file for one of the packages here. https://onedrive.live.com/redir?resid=5F3C0333C52D434B%216385
It seems to indicate the lack of package source for kb2707250.
I will try the other suggestion about downloading the ISO and trying the uninstall through it [after verifying checksum]
Thanks - Yuvaraj N
