Cannot Run eFilmLt.exe from CD

Found the solutions from this blog http://blog.echothis.com/2009/04/02/reading-ct-scans-with-efilmltexe-on-vista/

Reading CT scans with eFilmLT.exe on Vista
A bit off-topic but I thought I’d share. A friend of mine had this CT scan on CD and was having trouble reading it on his PC (sometimes it worked, sometimes not). And simply copying it to his hard disk enabled it unreadable. So I offered to debug why, and lo and behold, a quick Google search shows that lots of other people have reported similar problems (e.g., see here).
It seems that this proprietary reader (eFilmLT.exe), made by Merge Software, looks for a valid binary “DICOMDIR” file that points to the metadata for the particular scan images on the CD (e.g., the patient name, date taken, image filenames, etc.). Why this isn’t a human-readable format like XML, I have no idea.
Anyway, if you have a set of images that you can’t read:
  1. copy them to your hard disk
  1. download the attached zipfile, which contains all the relevant reader files (e.g. ,eFilmLT.exe, associated DLLs, “Profiles” directory, and configuration files). All these are (I think) independent of the particular CT scan on a given CD. I have *not* included “DICOMDIR” here by design.
  1. Overwrite your files with the contents of this zipfile.
Then try to launch the new eFilmLT.exe. It should pick up your DICOMDIR and now you can read your CT scans. This has been tested on Vista, probably XP works as well. Good luck.
And I copy the zip file here just in case.
