If you get certificate error when attempting to install 3rd party software on your S60 3rd Edition smartphone, it means that you haven’t enabled installation of unsigned SIS files. Go to Tools -> App. Manager, choose Options -> Settings and set Software installation to All and Online certif. check to Off.

i have a nokia 5530XpressMusic,still getting “certificate error
Same here: I have a Samsung i8910 HD running Symbian S60 5th, and I’m trying to install the TuneWiki application (I just downloaded “tunewiki.sis” from tunewiki.com a couple of minutes ago).
I have also tried to set the phone clock back to last year (this is suggested in some discussion forum in postings from 2007), but no avail.
Any hints on how to get by this error message?
Yeah…guys…the Application Manager Options (the 2 settings: All and
Off) do NOT work in regard to the Certificate Error problem. I’ve seen
this solution all over the Internet but it doesn’t work (and to tell you
the truth, the phone comes with those settings by default). So stop putting
this response on the forums because IT DOESN’T WORK.
P.S. I have a Nokia 5230
Even though we changed date ….and setttings .. it showing the error ???
My Set is Nokia 5530 Xpress MUsic
Previously there was no problem ..for instaling …. but when i deleted the the
some themes and tried them again it is showing ..error expired certificate ???© 2011 Phonesymbian.com. All rights reserved.
