I followed these directions:
1. Click Start, and then click Run.
2. In the Open box, type regedit, and then click OK.
3. Locate and then click the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Plugins\Extensions
Make a note of the contents of the Extensions key.
4. On the Edit menu, click Delete. Click Yes to confirm the deletion.
5. On the File menu, click Exit.
6. Search for and rename the file that is listed in the registry key that
you deleted in Step 3. To do so, follow these steps:
a. Click Start, point to Search, and then click For Files or Folders.
b. Click All files and folders.
c. Type the filename that you noted in step 3 in the All or part of the
filename box, and then click Search.
d. Right-click the file that is on the right pane of the search dialog box,
and then click Rename.
e. Type a new extension for the file, for example, Filename.bak.
NOTE: If you do not complete this step, the file may recreate the registry
key when you restart the computer.
7. Restart your computer.

The only thing under Extensions was ".pdf". I deleted that but the rest of
the instructions were confusing and I don't know what to search for???

By the way, I have no trouble downloading zip files on my laptop that is
connected to the internet through a hub along with my machine that is having
trouble. Is it possible that I have a setting on my machine that is
specifically blocking files with a .zip extension? Thanks for your help. I've
been working on this for days.
