How to uninstall Microsoft Silverlight from Mountain Lion? I'm trying to uninstall Silverlight and install an older version to get Netflix working again.

I updated Silverlight to version 5 not knowing that Netflix would end up throwing a N8109 error. Netflix FixIt recommended uninstalling and reinstalling Silverlight. 

Here is what I tried: 


Closed all browsers and dragged Silverlight to bin from /Library/internet-plugins
Also cleaned out Silverlight files from /Library/Receipts and /Library/Application Support
Tried using AppCleaner to find and delete Silverlight - Just ended up not being able to find it in any of the categories
Restarted my computer a bunch of times after every uninstall strategy - only in vain
Tried using Spotlight and Finder to find any traces of Silverlight, again to no avail.


Every time I try to install the silverlight.pkg (downloaded using the link Netflix provides while trying to play any video) the wizard detects a newer version of Silverlight on my HardDisk-Mac HD. 

The one thing I noticed was that no matter what approach I took, I always found Silverlight app on my Launchpad which again I couldn't delete straight out. 

Anybody been able to break through this wall?
I just spent an hour tearing my hair out, just like you. Deleted everything I could find, and still no luck! Fortunately, I found out about pkgutil when trying to research if other apps have similar issues. Run this command:

$ sudo pkgutil --pkgs


If com.microsoft.SilverlightInstaller shows up, it still thinks it is installed. I had to "clean" (kinda) the installation by using the following:

$ sudo pkgutil --repair com.microsoft.SilverlightInstaller


After that, I was then able to cause pkgutil to forget about the installation:

$ sudo pkgutil --forget com.microsoft.SilverlightInstaller


Hope that works for you!
