Unable to Install Silverlight Developer Runtime

Question

I installed VS 2010 Professional with full installation on Windows 7.

I installed Silverlight 5.0 separately.

When I create a Silverlight application, it asks to install Silverlight Developer runtime.

Before creating a Silverlight project, you need to install the latest version of Silverlight Developer

After loading the runtime, when I tried to install it, it was suggested that

a newer version of Silverlight is already installed

Therefore, I cannot set the runtime, and I cannot create a siverlight application.

I tried installing Silverlight 5, but asked to install Visual Studio Service Pack 1. The Microsoft Silverlight 3 SDK and Microsoft Silverlight 4 SDK are already installed on the system. Why does the SDK not include developer runtime?

What do we need to develop a Silverlight application?

Answer 1

Service Pack 1 required for Silverlight 5.

I suggest (based on my recent experience)

• Remove all the "Microsoft Silverlight" that you have
• Make sure SP1 is installed
• Install Silverlight 5 here: http://www.silverlight.net/

Answer 2

I was getting the same error. The problem was that the link that Visual Studio provided was for the 32-bit version, and I am running the 64-bit version. Some error indicating that if the installation failed, it would be nice ...

Here is a link to the 64-bit version of Silverlight 5 Developer Tools:

Answer 3

The simplest fix is ​​to remove and reinstall the Silverlight Developer Runtime, as shown below, when launched from the console window (for the 64-bit version):

Silverlight_Developer_x64.exe / qu

Silverlight_Developer_x64.exe

Please note that you need to wait for the silent uninstall to complete, so give it a couple of minutes before performing the reinstall.

By the way, this problem affects everyone who had a previous installation of the SL development environment installed and upgraded to Windows 8.1!

Answer 4

After installing the new version of Silverlight, you must also install the Developer version. With this, you can easily open your projects in Visual Studio.

Answer 11

If you install Visual Studio 2012 or (now), you will overwrite the .NET Framework 4.0 with 4.5, and applications created with 4.0 will need to be updated .. NET 4.5 is a replacement in place of 4.0, and not side by side.
