Please do have a look at http://support.microsoft.com/kb/278411

Have in mind that you cannot use WScript so use: Set WshShell = CreateObject("WScript.Shell")

And the <Console Command> could look something like:
RD /S /Q "C:\MyFolderToRemove"

There's an article in the Altiris Knowledgebase about how to execute a dos batch file from an .MSI installation.

And as AngelD said, I would also recommend to use the rd command.

Hope this helps

You should use VBScripting


[font="Courier New"]Function RemoveFolder()
Dim ShellObj_g, cmd
Set ShellObj_g = CreateObject("WScript.Shell")
cmd = "RD /S /Q " & chr(34) & & "C:\MyFolderToRemove" & chr(34)
RemoveFolder = ShellObj_g.Run( "cmd /K " & a_cmd & " & Exit", 1, True)
End Function


Mark function as Type 6 - run VBS function stored in a binary table or because is not so big Type 38 - stored in Custom action table itself.
If you use Type 6, you have to have .vbs file stored in a binary table.

jamsek19, why are you using VBScript to call a dos function...?

If you are going to use VBScript why not use the methods in the FileSystemObject.

'<CODE>VBSCRIPT<CODE>
Option Explicit
fnFolderDelete "C:\Temp" '<-- Edit and/or repeat this line for multiple deletes
Function fnFolderDelete(sPath)
Dim objFSO : Set objFSO = CreateObject("Scripting.FileSystemObject")
If objFSO.FolderExists(sPath) Then
objFSO.DeleteFolder sPath,TRUE
End If
Set objFSO = nothing
End Function

Hi cygan,
why don't you just use some entries in the 'RemoveFile' table?
See: http://msdn2.microsoft.com/en-us/library/aa371201.aspx
You can delete files (also with wildcards) and folders with it.

Nick, have you seen any reference to RemoveFile and read only folders? I have a package where I'm trying to remove some shortcuts and it's not working. I can't figure out whether it's because the folder is read only, or there's something else going on. I think I've had it work for r/o folders before.

not sure why you would bother with any of these, MSI has native functionality built into it to do just that.

check out the removefile table in the SDK for more details

The last column is of particular interest and it enforces doing during install or uninstall

using RemoveFiles table could be used but the msi would first have to remove all files using wild card (*) as the FileName for each directory and then last remove the folder.
