I used the $2 brand of interior mirror adhesive from Autozone to attach both wing window latches a year ago and have had no problems.

Make sure the glass is scraped with a blade, cleaned, and then wiped with rubbing alcohol before you attach the adhesive.
Follow the directions exactly, dont use too much adhesive, do it on a warm day, and hold the latches in place for at least a minute before releasing pressure.

Dont mess with them for at least an hour after installing.

That should do it...
