error message "error while installing. expected 1 instead of 0”

I am getting this periodic error message “error while installing. expected 1 instead of 0”

surprised that no one on google has ever had this error. it’s random. the error message

is not associated with any specific application. it just appears out of nowhere. i thought

maybe it was coming from finder or firefox. but it appears to not be associated with anything.

usually i am only running firefox. but to be sure i shut down other applications. but i still get this message

every five or six hours. i even went into activity monitor a few times and shut down anything that didn't need to be running. but i still get the message. anyone know what this means?

MacBook Pro 13″, OS X 10.11

SOLVED: For myself there may have been a couple sources of the problem. It has been a week now since I have had no error message displayed. One of the two possible causes was a file in "Library > LaunchAgents" called com.FHilEnLirpnWkxhyqvwjyFrmBeYMAgent.plist. I deleted this file and restarted the MacBook Pro. Unfortunately the error message still kept appearing. The next possible cause was in "Library > Preferences" called com.behenic.peglet.plist. I deleted this file and restarted my MacBook Pro again. It has been one week since then and I have not seen the error message display again.

this could be assoucated with the app "macs fan control". kind of this 'widget' app, that i use to turn off my fan when it won't stop running. because the "error window" is the same size. this is a big guess. however the error keeps appearing even when the app is off.
