Corel WinDVD - can't play Blueray - upgrade not installing  

I'm trying to play a blueray disc on my Sony Vaio VPCF22M0E/B Windows 7 laptop. First of all, when I try to open Corel WinDVD currently version 10.0.5.800 I receive the message from “LogicLayer” with “WinDVD information service is not yet ready. Please try again later”

So I went on the Sony website to download the latest drivers, WinDVD BD - 10.0.6.162 here-

Sony : VPCF22M0E/B updates | Download updates for VPCF22M0E/B

Then when I try to install the upgrade I get the following message from 'Update Module' - InstallShield Wizard-

This upgrade patch can't apply to your version of WinDVD. Setup will now abort...

So yeah, help. Is there something I'm not doing right here? I deleted some crapware off this machine when I bought it a few months ago, but don't think that is the problem.

OK now the software for running my new Logitech C170 webcam wont install. That's the 2nd thing in so many days. Do I have something set wrong somewhere? Why can't I install anything? I should have admin privelages. I was looking for the software to run the webcam today and I can't find it. Can't find that, can't find the drivers to play blue-ray, things are starting to not work on my new vaio and I don't like it.

EDIT no it's ok I got it to work, tried downloading the full version as opposed to the quick version, whatever the difference was.

Still need help with the bluray drivers/software though, will look into taht again in a day or so.
