Photoshop missing in Object Model Viewer (ExtendScript ToolKit CC) after installing 2015 CC

After installing Adobe Photoshop CC 2015 (32 Bit) on Windows 7, the entries for Photoshop in the Object Model Viewer (OMV) were missing.

I checked couple of properties before updating to CC 2015 – so I'm 100% sure that Photoshop was in the list just before the update.

How do I get the Photoshop Object Model entries back in the list (I have a 2-3 versions, but they all disappeared from the list, when installing CC2015)?

Thanks,

Andreas
