Can't install Silverlight Developer runtime

Question

I have installed VS 2010 professional with full installation in Windows 7.

I have installed Silverlight 5.0 separately.

When I create silverlight application, it asks for installing silverlight Developer runtime.

You need to install the latest Silverlight Developer runtime before creating a Silverlight project

After downloading the runtime when I tried to install it prompted that

newer version of Silverlight is already installed

So I cant install runtime and I cant create siverlight application.

I tried to install Silverlight 5 tools, but it ask to install service pack 1 for visual studio. Microsoft Silverlight 3 SDK and Microsoft Silverlight 4 SDK are already installed in the system. Why SDK does not include the developer runtime ?

What are the things do we need to develop a silverlight application ?

Answer 1

I was getting the same error. The problem was that the link that Visual Studio was giving was for the 32 bit version, and I am running 64 bit. Some kind of error mentioning that when failing the install would have been nice...

Here is the link for the 64-bit version of Silverlight 5 developer tools:

Answer 2

Service Pack 1 needed for Silverlight 5.

I suggest to(based on my recent experience)

1. Uninstall everything "Microsoft Silverlight" that you have
2. Make sure SP1 installed
3. Install Silverlight 5 tools from here: http://www.silverlight.net/
