Enable IE8 Add-on Programmatically

Question

I created a toolbar using Add-In Express for Internet Explorer and it installs fine, I'm using Wix. The only issue I'm having is I want to enable it after it installs. For some reason its disabled after it installs. If I go into Tools > Manage add-ons > Toolbars and Extensions, I see it in the list and I can enable it but I want to do this programmatically. It's IE8 on Windows XP and Windows 7. I tried Google'n it but with no success. I'm looking for anything that can do it: PowerShell, Registry Keys, .NET program, ANYTHING! Any help would be greatly appreciated.

Try adding or updating the following registry value,

Entry location: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\

Value Name: Enable Browser Extensions

Value Type: REG_SZ (String Value)

Value: yes

The value is yes.
