executebuiltin RunPlugin – check if found?

I’m using xbmc.executebuiltin(“RunPlugin()”) and if this plugin isn’t installed it will prompt you to install the plugin only if you have a repository installed that holds the plugin, if you do not have the plugin installed and also do not have a repository that has that plugin nothing happens and you just get “Unable to find plugin” in the log file.

My question is, is there anyway of knowing if this call succeed? basically I want to present a dialog ok box if the plugin wasn’t found at all in any repositories instead of it just doing nothing and putting “Unable to find plugin” in the log file.

Thank you in advanced!
