The very last slide in the appendix in my Creo Admin 102 talk had this workaround, and these documents from PTC that you can reference:
This is what PTC has to say about this: see CS27008,CS62951,& CS31709
The pvvercheck_ie.ocx ActiveX:
* This is a small program used for checking that the currently installed client release and datecode is not older than the one available for installation from the Windchill Server
* Launches the client upgrade prompt when a newer release is available
* Only installed by automatic download from the Windchill server through a file called pvvercheck_ie.cab located in platform specific sub-folders i486_nt_ie and x86e_win64_ie under the <wt_home>\codebase\wtcore\jsp\jsp\download folder
* This is not vital for displaying 3D Thumbnails in most cases
