Need Consistent workaround for Error - Unable to start Debugging.The SilverLight Developer Runtime Not Installed. Please Install a matching version
Monday, November 21, 2011 2:11 AM
In my project i need to deploy my silverlight app in different test machines(VM's) and if found issues, most of the time i will move the project to the corresponding machines and will debug. But most of the time i will face the error:Unable to start Debugging.The SilverLight Developer Runtime Not Installed. Please Install a matching version for many times.
The workaround for this issues like,
- Uninstalling the current dev runtime and re-installing the same
- Uninstalling the silverlight tools and reinstalling it, etc.,
But these workarounds are not solving the issues everytime. Also it leads to a productivity loss, since i couldn't find a consistent soln. Can anyone explain what is the root cause for this issue and the proven workaround for this issue for every scenario's?
Thanx in advance

syed, I can able to debug sometimes with the workaround i have mentioned. But not all the times. Also this is not only happening in the VM's, its happending in mine and my peers developement environments also.

How is this issue going?
Could you post your VisualStudio version, Silverlight runtime and developer runtime version here? Then we can verify if they match with each other.
The lastest is Visual Studio 2010 sp1 and if you have already installed visual studio sp1 it installs silverlight tools for visual studio sp1 automatically.
You can get the latest Silverlight runtime from below link (4.0.60831.0)
The lastest silverlight developer runtime can be download from
