Deploy custom start page with vsix

Hi,

I want to deploy our custom start page in Visual Studio 2010.

I have created a vsix with our start page and a pkgdef file with this registry keys:

[$RootKey$\BindingPaths\{DAC23E13-EFD3-49AF-9CE8-18D8F7D10238}]"$PackageFolder$"=""
[$RootKey$\StartPage\Default]"Uri"="$PackageFolder$\ourStartPage.xaml"
[$RootKey$\StartPage]"NewsChannel"="http://ourSite/?feed=rss2"
[$RootKey$\General]"OnEnvironmentStartup"=dword:00000005

The extension is correctly installed but the configuration (rss stream, display start page at startup) is not applied.

I have tried to replace $RootKey$ by HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0

but it doesn't work!

How can i do to apply the configuration?

Thanks
