I'd claim that this is not the real question. The real question is, instead: "What specific error did you get when adding a single minus sign to the program?" Please try answering that question also. > The answer is? I'm not sure I understand the question. What do you mean by "given"? Perhaps "already downloaded locally"? If so, the obvious answer is "Go to Add-Remove-Programs. Uninstall. Then double-click the MSI files." If that is not a good answer: why not? If you want that automated: write a batch file, invoking "msiexec" as necessary. Regards, Martin -- http://mail.python.org/mailman/listinfo/python-list
