I can not find the site where to download ms Powerpacks 10, I use it with vb.net 2010.
Microsoft.VisualBasic.PowerPacks.Vs 10.0.0.0 is included with Visual Studio 2010.
The default location is C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper\Packages\VBPowerPacks\en\VisualBasicPowerPacksSetup.exe
C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper\Packages\VBPowerPacks\en\VisualBasicPowerPacksSetup.exe
I believe 10.0 is not a real name, but it is actually 3.0. Download link, which can be found below

However, from this post it seems to be included in VS2010 anyway!
