Hello Tim,

I have been trying to disable Javascript using my Add-on toolbar for which I have to access Registry,..

I got this error on Windows 7 but not on Windows XP:

Hi Pratibha,

Please make sure that the issue can be solved by turning Protected Mode off. If it can, then you need to use the ProtectedModeApi class to get a writable registry branch:

AddinExpress.IE.ADXIEProtectedModeAPI protectedMode = new AddinExpress.IE.ADXIEProtectedModeAPI();
string anHKCUKey = protectedMode.GetWriteableHKCU();
