I bought Visio 5, then Visio 2003 since upgrading from 5 was not allowed. I then upgraded to 2007. we had moved and a few of my disks were damaged, incuding my Visio 2003. Now I cannot install my 2007 on my new Windows 7 laptop. Visio 5 is way to old to install, my 2003 disk is broken, and my 2007 only looks for "approved" MS Office files. I called Microsoft and was told the disk is out of print and I am out of luck.
