Visual Studio keep asking to install latest silverlight developer runtime, when it is already installed

Question

I developed a Silverlight Application (SL4). The application is already deployed (been working for last 3 months and still working in IIS).

I can't open the solution anymore. VS2010 keeps promting to install the latest version of Silverlight Developers Runtime! Everything is already installed on my work laptop (I developed the application on my work laptop and deployed it). I copied the same solution to my home laptop (which is offline, no internet connection), the solution opens right away in Visual Studio 2010 and eveything works just fine, so there is nothing wrong with the source code (no version conflict, no other smart guessing here).

Is there any Visual Studio or Silverlight update, destroying the development environment, that I am not aware of?

Answer 1

I had the similar problem. Every time I tried to visit a link and install thing I got the same. However, I asked colleagues and they suggested me to install things in the following order:

1.Uninstall everything that has name "Silverlight"

2.Install "Silverlight_5_Toolkit_December_2011.msi"

3.Install "silverlight_5_sdk.exe"

4.Install "Silverlight5_Tools_SP1.exe"

5.Install "Silverlight_Developer_x64.exe"

I had all that packages downloaded in my company, so you will need to find them in internet by yourself. From what I've seen, they are all available. The only matter is direction of installation. This one helped me.
