You either need to get it signed by yourself (a painful process) or hunt for a singed version somewhere. Requirement : Genialsis pc application download it by searching on google.

I hope this would work for you and others who still have the problem too. security Off" to ON & "INSTALL ROOT CERTIFICATE" only once.. but remember always make ONLINE CERT=OFF & SOFT installation= ALL & reduce the year... Hint: You may have tried installing unsigned application. You can use self-signed certificate or developer certificate from Symbian Signed to sign your application.

When I was about to give up, I thought of the last try – to uninstall all the Nokia software from Vista, reboot the PC, install the Nokia Cable Driver (for Windows 2000, XP and Vista) followed with Nokia Software Updater.

Only then, the NSU finally detected my N73 ME in Windows Vista!

Although the latest Nokia PC Suite v6.85.14.1 has no problem to detect and work perfectly with my phone, the latest NSU v1.4.23 kept on fail to detect the N73 ME connected via USB cable!
