Error intalling sis files on my Nokia 71

[krish1704]

Hi there,

I am actually facing a problem installing *.sis file on my Nokia E71.

Error Message read:-

"Certificate Error - contact the application supplier".

Please help.

Thank you.

First thing to do is;

Menu>Tools>Application Manager
then press <options> button, select <settings> ,
enable all software installation and disable online certif. check.

If that does not fix the problem,then it seems by just changing the date on your phone to 2006 it will allow you to install the themes,then just reapply the correct date afterwards.

"Most of Nokia S60 phones need to "go back" to a date prior to 12-6-2006 to be able to install certain software as Nokia's Lifeblog, for example. Stupid but it is on Nokia's FAQ's".
