With version 1700 I looked in the registry under the path "HKEY_CURRENT_USER\Software\ESRI\Explorer1700\InstallDir" to find the path to where it was installed. I then appended "bin\e3.exe" to the path and used "ShellExecute" to startup ArcGis Explorer. For version 1750, that registry path does not exist anymore.
How do I find the path to the ArcGISExplorer executable so I can start it from a separate program?
