Getting rid of 'Installation security error'
Published by Steve Litchfield at 8:56 UTC, February 1st 2006
Q. Having bought a new Nokia smartphone, I'm having problems installing most of the programs I've downloaded. The error message is 'Installation security error, unable to install'. I spoke to Nokia and they say there is no security feature to prevent software installation.
A. The Nokia support team are mistaken, the newer Series 60 smartphones all have a security system in place for applications. By default it's set to just allow the installation of commercial programs that have been 'Symbian signed'. What you need to do is go to 'Tools | Manager | Options | Settings' and set 'Software installation' to 'On'.
While you're there, it's well worth setting 'Online certif. check' to 'Off', if it isn't already, as this may also catch you out when installing software from Nokia in the future. Now try installing the third party programs again and all should be well!
I am trying to get my new N95 working with DataViz RoadSync (with MS Exchange 2003 SP2), which appears to be working great - with the following caveat:
I can't find a way to install a self-signed certificate (created by MS Small Business Server 2003) to prevent the annoying cert prompt when it synchs.
I have followed a few posts, but to dead ends.
When I try to install an exported .cer file (by Bluetooth transfer or using File Explorer), I get a 'file type not supported' error. Similarly response with a .p7b file.
Can you assist or advise in how I might fix this?
