Deleting a folder structure with all files and subfolders using VB Script

By default WISE can’t delete a folder structure with all files and subfolders. The technologie of MSI is designed to delete only these components by uninstalling, which were installed.

With the following VB-Script can do just that. It makes sense, that the script uses a property of the directory-table. The example uses the “JUNIPER” directory, which will be deleted by the script.

Option Explicit 
Dim WshShell,SystemFolder,Fso,strFolder, strFile, ret
 
' Set the property
strFolder = GetAProperty("JUNIPER")
 
' Delete the last character at the end of the string 
' -> example: C:\Programm Files\Test"\"
' For a correct deleting of a directory-property, 
' the backslash at the end has to be deleted
strFolder = Left(strFolder,Len(strFolder)-1)
 
' Environment variable reading 
set WshShell = CreateObject("WScript.Shell") 
set Fso=createobject("scripting.filesystemobject") 
 
' Delete the folder
If Fso.FolderExists(strFolder) Then 
ret = Fso.DeleteFolder (strFolder,True) 
End If
 
Set WshShell = Nothing 
Set fso = Nothing 
 
' Getting a property
Function GetAProperty (PROPERTYNAME)
dim szStringVal
szStringVal = Session.Property(PROPERTYNAME)
GetAProperty = szStringVal
End Function

The script must be implemented in the “immediate” section of the MSI-Script. In my example it has to be on the latest position – immediately before the completion of the installation.
