I would respectfully disagree.
The correct thing to do would have been to submit an official support ticket. This is hosted and indexed on our website. This would be our preferred method of customer support, even if we end up referring back to the same support materials. The reason for this is we can then offer bespoke advice, should it be needed.
You don’t need a password for support or fixture requests.
The reason the software downloads are behind a customer log in wall is that without it we would have absolutely no idea who is downloading our software. This method enables us to directly communicate with our users for things like major software updates and patches.
In your specific scenario the software doesn’t need “patching” at all. It’s the computer that needs some help in it’s configuration, and for the record, the Vista installer normally does this automatically.
As for the tech note, there are 100s of variables that often need to be investigated or checked if for some reason the installer isn’t updating the drivers, hence why we ask our users to take some troubleshooting steps with us. This methodology is no different to any other technical support request you may encounter with any other company or product.
I assume you got it working ?
If not, submit a support request and we can further assist in those channels.
