Hi,
I was using v4.09.4471 when the same problem occured.
I just upgraded to v4.10.4570 and the same problem still exists ( using WIndows 7 32-bit ).
The script I used :
Set objShell = CreateObject("Wscript.Shell")
objShell.CurrentDirectory = "C:\Program Files\CCleaner"
objShell.Run "CCleaner.exe /AUTO", 7, True
wscript.echo "This should not be executed before CCleaner closed"
