Can't unzip downloaded Premiere Elements 11

Forum experts,

Downloaded Software: Adobe Premiere Elements 11 (full version... not trial

version)

Computer: Dell XPS M1330 with Win 7

Available hard disk space: 70 GB

When the installer program (PremiereElements_11_LS15_win32.exe) tries to

unzip the download files , it produces a pop-up error saying, "A problem

occurred while extracting some files. Check available space on your

computer and write privileges on the destination folder." (See attached

screen shot).

This happens regardless of where I save the file. I've tried unzipping to

the desktop, to a directory one level below the C: root, and to a directory

in "my documents"... but the result is the same.

I've also tried running the unzip as administrator. That makes no

difference.

I have 70GB space open on my HD, so space is not an issue.

Looking in the extracted files that "survived" the unzip, I see that many

of them (including the initialization files) have zero bites size. The

setup.exe file is there, but it chokes when it tries to read the blank

init. files. (See attached screen shot).

What's wrong with this unzip process?

It's bad enough that the download took almost 8 hours... Now I've been

pulling my hair out with this unzip problem for another 4 hours. Please

help.

Thanks everyone...

======================

Update:

I tried disabling my virus protection before running the extract file (as suggested in article http://helpx.adobe.com/tech-comm-suite/kb/error-problem-occurred-extracting-archive.html).  ... But that had no effect.

Please help!
