I've recently installed Opera, version 10.01. When I go into the settings for download studio and click the "Install changes into Opera" button, I get the message "Unable to change menu settings - please check the version of Opera that you are using, and that you have the required permissions."

I tried running DownloadStudio as Administrator (on Vista x64) and got the same response. The integration to catch downloads works, but I don't have any DownloadStudio menu, there is nothing added to the context menus, etc.

I'd appreciate any tips if there is a way to get this to work.
