Tried uninstalling and re-installing, no luck. It seems to be a VST2 file.
Ran the log, but it didn't seem to log anything unusual... although it did delete Kontakt.dll registry key (probably from the disable option on the popup). Here's the snippet from the Kontakt player log (38):

EDIT: Dove a little bit deeper, and found that actually, the full log stops right at the last line copied down below. Again, it seems like it's not establishing contact with the main point?
