In the registry Mozilla plugins cannot be deleted but one is blocking installation of MS Silverlight update. Any suggestions?
Microsoft has been trying to update Siverlight for the past few weeks - each time failing. It says that HKEY_LOCAL_MACHINE\SOFTWARE\MozillaPlugins\@Microsoft.com/NpCtrl,version=1.0 is the problem. I have tried to delete it & the whole Mozilla key but I get 'Error while deleting key. Access is denied', in every case. There are 14 items under MozillaPlugins.
I reinstalled Firefox to see if it would 'kickstart' the string, without success.
MozillaPlugins:Name (Default); Type:REG_SZ; Data:(value not set). Windows 7 Home Premium.
I am the main administrator - confirmed in cmd - but anything I enter into Permissions is refused.

You will have to change the permissions of that key via the right-click context menu.

Thank you. I am obviously not doing the right thing as all of my suggested entries, to change the Permissions, are rejected. For instance, what is the name of the object? I have tried various permutations without success.
Post Script: have just run Microsoft's Fixit (kb2608523) & it did. I don't need to worry about deleting the Registry Key, now

Did you give yourself write permissions for this registry key?
You may nee to go up a level and apply the permission to sub keys:
- HKEY_LOCAL_MACHINE\SOFTWARE\MozillaPlugins
