UAC with UPX Shell

I have been building a UPX Shell GUI for UPX, which up until a few hours ago was working very well yesterday using two different methods to starting a console application (UPX) and redirect stdoutput.

During continued development today when I run my UPX Shell UPX compresses or decompresses the file but reports eithe开发者_如何学运维r an IOerror which I assume is caused by UAC in Windows 7 or a IORename errors when -k (backup) is an option. When I run my UPX from the commandline ( no administrative access ) upx runs just fine.

I am testing two different ways to run a XPX commandline. First I am testing the function "Sto_RedirectedExecute" was written by Martin Stoeckli and is part of the site: http://www.martinstoeckli.ch/delphi/. Secoond, I am also testing PJConsoleApp.pas written by Peter Johnson of the Delphi Dabbler: http://www.delphidabbler.com/software/consoleapp?mid=3.2. Peters classes are designed to be used to control the execution of child console application processes and to redirect input and output where required.

Using Sto_RedirectedExecute, UPX reports this: Ultimate Packer for eXecutables Copyright (C) 1996 - 2010 UPX 3.07w Markus Oberhumer, Laszlo Molnar & John Reiser Sep 08th 2010
