Find EModelViewer.exe path.

I have an old VB6 Program that Starts the Emodel viewer when the user puts in the job name.  in the VB6 program, I hard coded the file path.  the problem with this is that this program is used by SolidWorks users and and Non Solidworks users.  This means that the File location is different for different users, and I have to go in and change the code everytime we get a new version of eDrawings.  I am currently rewriting this as a C# .net application and I was wondering if there was a way to find the Path of emodelViewer.exe.
