Ovi store update not working

[DPH]

Has anyone else encountered this.
When I open Ovi store on my phone, it advises there is an update and I need to get this before proceeding.
However, the install fails each time with the error message' Installer already in use.'
I have tried installing via Ovi suite, still happens.
Tried going direct to ovi store via the mobile browser, same result.
Ovi store does NOT appear on my installed apps list so cannot uninstall, then reinstall.
Any ideas?

I had that - IIRC the trick was to power off,power on, install the update, then power off/on again before using the store.

I was having the same 'installer in use' for other apps too, so I did a hard reset (backed up first) and all is fixed.
