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 ?

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:

Thank you so much! I am in the same boat as @DanielSchilling ... what a frustrating journey. Makes you twitch thinking of the issues that a client might have when trying to install Silverlight... – Josh McKearin Mar 19 '13 at 12:24

The simplest fix is to uninstall then re-install the Silverlight developer runtime as shown below when executed from a console window (for the 64 bit version):

Silverlight_Developer_x64.exe /qu

Silverlight_Developer_x64.exe

Note that you need to wait for the silent uninstall to complete, so give it a couple minutes before executing the re-install.

By the way, this issue is affecting everyone that had a previous installation of the SL developer runtime installed and upgraded to Windows 8.1!!

After installing a new version of Silverlight you have to install the "Developer" version, too. With this, You can open your projects in Visual Studio without any problem.

Not quite right. You must not install new versions of non-developer Silverlight. If you get it as a stupid update you have to delete it and reinstall developer version. You can't have both. – The incredible Jan Apr 12 '17 at 12:00

Uninstall Silverlight version 5 and then reinstall it using the link provided from visual studio.

This worked for me.

For Visual studio 2013 and windows 10, make sure you debug/start your application with Microsoft internet explorer. Debugging with Edge will result in the following error message: Unable to load the Silverlight developer runtime.

If you install Visual Studio 2012 or (now) release version you will overwrite .NET Framework 4.0 with 4.5 and apps created with 4.0 will need to be upgraded. .NET 4.5 is an in-place replacement to 4.0 not a side-by-side.

You are incorrect. Apps "Created with 4.0" will run *perfectly fine* under 4.5, just as they are. The fact that 4.5 is an 'in-place' update over 4.0 has nothing to do with existing programs running just as they did, in 99.999% of cases. – Andrew Barber Sep 21 '12 at 21:09
