I am trying to down loaD a trail version of windows 7 i have vista and i have 32

The 90-day Trial of Windows 7 Enterprise is still available 32bit and 64bit.

To burn it to a disk after download you will need ISO burning software.

Magic ISO is free.

When the 90 day evaluation trial period is almost expired or ended, log on to Windows 7 desktop, and open a Command Prompt window (i.e. type Cmd in Start Search and hit Enter).
Type or cut and paste following command into the command prompt, and then hit Enter:

slmgr /rearm

Note the space in front of the forward slash. Has to be exact.
You can rearm at least 4 times= 1 year.
