I have visual studio 2008 Team System Team Suite installed on a windows xp sp2 machine.

I have installed the VS_SilverlightTools_Alpha_Setup.exe and the Silverlight 1.1 Alpha Refresh.

 However - when I try to open the SilverlightControlsStarterKit.sln or make a new Silverlight project I get the error:

Cannot open ... path to csproj file... Project type not supported by the installation.

I see that many people have this problem but noone seems to have a solution! Is there anyone here that has solved this?
 

 Try the following ~

- regsvr32.exe "%vs80comntools%\..\IDE\projectaggregator.dll"

- Install this one.

I have done this (even though the file you link to is for VS2005) and I still have the same problem. I checked the version of my Microsoft.VisualStudio.SilverLight.dll as stated in this post http://silverlight.net/forums/t/4181.aspx and it is correct: 9.0.20706.18 

I have tried everything I found on Google but still it does not work. 

 I finally fixed it by running devenv /setup

 However now I have other problems.... but I look for replies before I post these.
 

I installed on 2 systems; one worked no problem and the other gave me this error. 

Both have VS2005 installed so I'm not sure why the problem on one and not the other. I also noticed that 'Silverlight Projects 2008' didn't show up in the list of installed projects on the system that gave the problem.

devenv /setup worked for me.

 I am getting the same problem and have tried all of the solutions from this thread ( excluding the VS2005 update since I'm using VS2008 ). devenv /setup didn't work and the regsvr32 fix didn't either.

Anyone know how to fix this problem?

Thanks!

What about this one?   devenv.exe /resetskippkgs
