I make my living as a graphic designer. Many of my clients ask me to do PowerPoint presentations for them. As such, over the years I've kept multiple versions of PowerPoint so that I can use the exact version my client has. In recent years I've had Office 2002 and 2003 installed on the same machine without any problems whatsoever. I am getting ready to buy Office 2007. Due to some Microsoft installation problems I was having on a new hard drive, I mentioned to the tech I was working with that I will be soon be installing Office 2007 on my computer. I will continue to need and use 2003 and sometime 2002. He told me it was impossible to have multiple versions of PPT (and perhaps Office as a whole) on one machine. I disagreed since I've run 2-3 versions of Office on one machine for years. Is this something new with Office 2007 or more specifically PPT'07? If so, this really limits my client base. Regards, Jodi-
