  1. This article is very helpful in solving the silverlight and Java problem on my computer. Thank you very much

  2. I had the same problem. The answer is to download the file MicrosoftFixIt.ProgramInstallUninstall.RNP.RUN -from Microsoft – once downloaded, run it. Tell the program you can\’t Uninstall Silverlight – actually it will find and fix the corrupt files for you. Once done, just download and install Silverlight and you should have no problem.

  3. I am having the same problem and have done absolutely everything above and it still will not install. There is nothing left in the registry connected to silverlight. When I click run to install the box pops up and status bar goes really fast then disappears yet in never goes any further and there are no system files anywhere. I am at a loss and very frustrated because i am wasting money on netflix and cant even use it. I would really appreciate any help.

  4. The “Silverlight Eraser” tool at the Jigsaw Explorer web site quickly and completely uninstalls any corrupted Silverlight installation without manual steps. You can find it by Googling “silverlight eraser uninstall”.
