"After sequencing RSSOwl 2.x with App-V you may be able to launch RSSOWL during the monitoring and the launch phase, however after the second launch (and subsequent launches) the app fails to start with an application-specific error: "There are no more files". This occurs due to a sharing violation with initial configuration file and directory which needs to be opened for Read/Write access," explains Microsoft.
1. Add an exclusion for %CSIDL_PROFILE%\.rssowl2\ prior to monitoring, by going to "Tools" and then "Options" in sequencer. Then click "Exclusion Items" tab. 2. During sequencing, let RSSOwl launch after it finishes installing during monitoring phase. Then click through (skip) Launch window. This'll ensure all user settings don't get capture and get regenerated for new users and get properly routed to their profile *.PKG files.
