MediaDent

Explanation of Additional Properties
The Additional Properties box has some variables that you can set:

MediaDent Version 4 or 5: Enter either 4 or 5.  In Version 6.6, the bridge was overhauled to include support for MediaDent v5. 

Text File Path: Only used with version 5.   Patient data will be written to a text file.  You must make sure that the path specified is valid on all computers and that the user has Windows permission to write to that file.  Warning! The default text file path is actually a poor choice because Vista does not normally allow users to write directly to the C drive.  A better choice would be: C:\Mediadent\MediadentInfo.txt  But you would have to make sure to create a C:\Mediadent folder on each workstation and assign full read/write permissions to that folder in Windows.

Image Folder: Only used with version 4.  After upgrading to version 6.6, the Image Folder may have to be reentered.

Also, you might have to specify a fully qualified path for the file to open in the text box further up.  Like this:  C:\Program Files\Mediadent\Mediadent.exe, or whatever the usual path is.  The disadvantage of doing this is that the path might be different on 64 bit machines.  So try the simpler path as shown above first.
