trying to install Microsoft Silverlight on my computer but keep getting this error: MSI (s) (90:F8) [13:18:15:124]: Product: Microsoft Silverlight -- Error 1402. Could not open key: HKEY_LOCAL_MACHINE32\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION. System error 5. Verify that you have sufficient access to that key, or contact your support personnel. I have checked in regEdit.exe that I have permission for this folder.

This issue can occur due to remnants of pervious installed Silverlight files. I would suggest you to completely uninstall and reinstall Silverlight and check if it helps you fix the issue. To Remove Silverlight, follow the steps below:

Press Windows key + X, click Control Panel, and then, under Programs and features, click Uninstall a program.

In the list of programs, click any earlier version of Silverlight such as "WPF/E" (codename) Community Technology Preview or Microsoft Silverlight, and then click Uninstall.

After the uninstalling process is complete, you can install the latest version of Silverlight.
