In the following environment:
-VS2012
-Windows 7 64bit
-Microsoft Silverlight 5 SDK
I have created a few lightswitch applications in VS2012 but I am running into an error when attempting to create a new one or open an existing lightswitch project. I receive a pop-up that says "unable to find a version of silverlight developer runtime installed".
There is a link on the pop-up which starts a download but after downloading it, I still receive the same error.
I was able to fix the issue by doing the following :
I went into "Uninstall a program" and noticed that I had 4 different Silverlight related items installed.
Microsoft Silverlight
Microsoft Silverlight SDK3
I just uninstalled the first item, "Microsoft Silverlight" then reinstalled the appropriate (32 or 64 bit) Microsoft Silverlight SDK5 from the following link: http://www.silverlight.net/downloads .
Don't use the link that is given in VS 2012. Doesn't work.
The best way I have found to find the most current Silverlight 5 Developer Runtime or End-User Runtime, is to search the downloads for the latest Silverlight bits. All other suggestions seem to take you on a wild goose chase depending on what version of Visual Studio or OS you are using.
Just look for the latest "Security Update for Microsoft Silverlight" entry.
