InstallExecuteSequence not work when processing some on C:\Program Files

[alicera]

I write a InstallExecuteSequence and use it to delete the folder aa that I install with installer.
It cant not work. (I have add some file on folder aa)

By the way, if I assign the path to C:\myfolder\aa
it can work

<Binary Id="CommandPrompt" SourceFile="C:\Windows\System32\cmd.exe" />
<CustomAction Id="DeleteFolder" BinaryKey="CommandPrompt" 
      ExeCommand='/c rmdir /s /q "C:\Program Files\aa\"' 
      Execute="immediate" Return="ignore" Impersonate="no" />

<InstallExecuteSequence>
<Custom Action="DeleteFolder" After='RemoveFolders'>Installed</Custom>
</InstallExecuteSequence>

Ending a command line with \" can create issues with cmd.exe string parsing. You need to escape the value properly.
