Purpose
You want to read a registry value
 

Solution
Use the "WScript.Shell" object

Example
We read the installation path of "excel.exe":
 
GuiXT 

CallJS x = _
  RegValue "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\excel.exe\"
Message "&V[x]"

JavaScript 

		

		

		

		Remarks

		We need the ending backslash "\" since we read 
		the "Standard" value:


		

		

		In order to read a particular other registry value, e.g. "Path", use 
 

		GuiXT

CallJS x = _
  RegValue "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\excel.exe\Path"



		

		In order to handle non-existing registry keys use the JavaScript 
		try/catch mechanism:
