Head to the Heart - Register ActiveX

I've continually come up with an issue while building the Head to the Heart powerpoint slides in my MSOffice 2007 Virtual Machine. It keeps complaining when I open it that an ActiveX is not registered, but doesn't say anything else past that. There are shockwave flash objects used in the powerpoint, but they visible on the slides as flash objects and listed as registered in the developer tab of ActiveX items. Seems tied to them though as the music or filmclips they should be bringing in disappear if you save the powerpoint once opened with the registration error.

Turns out Flash is NOT registered in Internet Explorer (since it's a custom VM just for Office), so the fix was to simply reinstall Flash into IE.
