I would like to use my USB Stick at work with the portable apps software installed http://portableapps.com/suite. The problem I am having is that when I go to load any of the software I get the message you do not have enough administrative privileges on this computer. I was under the impression that these programs ran from the USB stick so that their would be no need to install anything on the computer they are being run on?

I have done a little research and come across VMWare Thinapp but this is not Freeware. Does anyone know if their is a Freeware program similar to this or perhaps a work around so that I can use the programs at work? I get the impression that .exe files are somehow blocked.
Thanks in advance for any info / advice.
