Why can't I update preinstalled apps giving error package was signed correctly?

[AC Question]

cannot update preinstalle apps giving error package was signed correctly

I cannot update any of my pre installed apps on my micromax a350..
Whenever i try to update it..it give a
"Package was not signed correctly please uninstall and install a fresh copy" everytime...
I have tried all the options installing from pc and uninstalling and installing again and disabling and updating bit no luck..
My phone runs on android 4.4.2.

Any anyone tell me how to remove that error or give a link with latest update of apps like hike messenger which gives me same error as above..

Please help me to solve this problem...

Welcome to Android Central! Are you trying to update via Google Play Store, some other app store, or just via apk file?
