Installing iMovie 7.0.1

Thanks but the URL you give (<http://mac.softpedia.com/get/Video/Apple-iMovie.shtml>) refers to downloading iMovie 7.1.0. If I try to install iMovie 7.1.0, I get a message:
"You cannot install iMovie Update 7.1.0 on this volume. An eligible iMovie application was not found in the location / Applications." The requirement for the install of iMovie 7.1.0 is iMovieHD 7.0.1.
I cannot find any download sites for iMovieHD 7.0.1. Yes, I can find iMovie 7.1.0 but I need iMovie 7.0.1. This is the version of iMovie I need but can't find.

I have iLife '08. I bought it specifically to solve the iMovie upgrade issue I had. But the installer will not install iMove 7.1.0. When I try the install from iLife '08, I get the message: "You cannot install iMovie Update 7.1 on this volume. An eligible iMovie application was not found in the location / Applications."
The requirements for the install are iMovieHD 7.0.1. I have iMovie 6.0.3. I tried re-installing iMovie 6.0.3 from my iLife '06 disk and trying again to install iMovie 7.1.0 but I get the same message. I think I need iMovieHD 7.0.1. I cannot find any download sites for iMovieHD 7.0.1. Thanks for your help,

Google coughed up this URL for iMovieHD 7.0.1:
<http://www.fileavenue.net/index.php?action=categories&cat=2&pl=mac>.
But Trying to install the iMovieHD 7.0.1 gives the SAME message:
"You cannot install iMovie Update 7.0.1 on this volume. An eligible iMovie application was not found in the location / Applications."
Life is a test. I have no complaints against iMovieHD 6.0.3 either.
