It's not there, so I asked. I had a problem during installation: my windows xp keeps telling me that this program doesn't pass the windows verifiction test. I keep going and at the end my computer crashed. And I wasn't able to boot it due to continuous crashes. So I ended up to rebooting the last working configuration and it worled. But I can't access to my hfs dognle and in the program menu I can sse the voice Paragon HFS+ for Windows 7.5 with only the help inside. And I have no clue on how to remove it except deleting from my programs folder.
