It's been years since I've run two versions at the same time. I think I did it at a company I was at years ago - pre 2000.
As an independant consultant now, I may need to have 2005 and 2006 running at the same time, since some of my clients are not yet upgrading.
I have recieved 2006 in the mail, but have not yet installed it in addition to my 2005.
Does anyone have any recent experience running both at the same time?
I know darn well not to open a file in 2006 that I need to read in 2005.
