I am having issues deleting a registy string value that contains a path... C:\DirectoryPath

The registry key is... HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Folders\

The string value is... C:\DirectoryPath

I have used \ and \\ between the two, but am still getting errors.

I expect it is just an issue of string structuring, I can easily do this in cmd form, but this was a new challenge.
set WshShell = CreateObject("WScript.Shell")
 
strValue="HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Folders\C:\DirectoryPath"
WshShell.RegDelete strValue

The simple answer is: it cannot be done. The WSH does not support deleting values that have backslashes in their names: http://www.ureader.com/msg/1677274.aspx.

But the good news is, it can be resolved by using WMI instead. Try the following for your key (it works, I tested):

Const HKEY_LOCAL_MACHINE = &H80000002
Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\default:StdRegProv")
 
strKeyPath = "SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Folders"
strKeyValue = "D:\test\test\"
 
oReg.DeleteValue HKEY_LOCAL_MACHINE, strKeyPath, strKeyValue
