On the Windows 7 box make a new folder under C:\Program Files\HyperTerminal for 32-bit and for 64-bit make a new folder C:\Program Files (x86)\HyperTerminal

From a Windows XP box and copy the following 3 files to the folder that was just created on the Windows 7 box:

C:\Program Files\Windows NT\hypertrm.exe
C:\WINODWS\system32\hypertrm.dll
C:\WINODWS\Help\hypertrm.chm

Now just run hypertrm.exe and HyperTerminal is on Windows 7.

If you want to have HyperTerminal on your Start Menu just create a shortcut to hypertrm.exe and put it inC:\ProgramData\Microsoft\Windows\Start Menu\Programs and when you go to All Programs under the Start Menu HyperTerminal will be there.
