I'm afraid I don't know. It depends on your computer and the software you used to download. On the PC, some browsers will download to c:\temp by default. But not all. And most can be configured, so it could depend on how you set things up. As for the Mac, I'm not familiar with the conventions at all.
If you have a disk-searching utility on your computer, look for "TrajectoWare10.msi". (Use Windows Explorer if you have a Windows machine, and choose the Search view.)
