Windows 7 has some new (for me) ideas about "system folders". Old programs not designed for Windows 7 might try to store application data in their own programs subdirectory. In your case it's an old binary in the OCMloader subdirectory. If you can't get an update for this tool modify its compatibility settings (right click on the binary) and pick XP SP2 or similar.
