Capture.exe not found

Hi there
I have seen that this problem has been flagged already, however the fixes suggested do not apply/work for me. I have never had a version of MARK installed on my computer so there isn't any old versions to remove. I've tried the link for the most stable version but the page doesn't exist. Any help much appreciated.
