If the Virtual CD Explorer Extension is available for virtual CDs and virtual CD/DVD Drives, but not for ISO conform images, an application has been installed and registered the corresponding file extension (i.e. nrg) during installation.

Please deactivate in Virtual CD Settings (Virtual CD Quick Start icon -> Settings -> Supported ISO images -> tab Supported ISO images) the corresponding file name extension and confirm with OK. Now activate the corresponding file name extension again. This will add the Virtual CD Explorer Extension to the above-mentioned application.

Please note that some functions of the Explorer Extension might not be available (i.e. the icons of Virtual CD) because the above-mentioned application should not be replaced by Virtual CD. (I.e. if Nero has been installed the file extension nrg should used with Nero by default.)
