In versions prior to 2.0.1 (currently in Field Test mode), the Formativ installer would disable the association between VBS/VBE files and the Windows Script Host. It would reassign the association to an application that displays the message you mentioned.
I’m not sure why you would start to see this message now, other then whatever has been done during the upgrade has caused a VBS or VBE script to be automatically executed. The message box you mention above will contain the name of the VBS file some process is trying to activate.
You can re-assign the association from the Formativ Windows Control Panel applet – press the ‘restore association’ button under the additional security section (and ensure the ‘disable association…’ option is unchecked).
I hope this helps.
