FP9 won't install after uninstall

Question

I'm using swfobject and expressinstall to load a Flash8
movie.
I have expressinstall working in Firefox, but not in IE7.
The Adobe autoupdater loads the update files but Flash Player
can't be found.
Here's my HTML:
<div id="fcmain">
<div id="fctext">
No Flash Content
</div>
</div>
<script type="text/javascript">
// <![CDATA[
var version = deconcept.SWFObjectUtil.getPlayerVersion();
if (document.getElementById && (version['major'] >
8)) {
var so = new SWFObject("fddmain.swf", "fddmain", "1100",
"660", "9", "#FFFFFF");
so.addParam("quality", "high");
so.addParam("wmode", "opaque");
so.addParam("allowscale", "true");
so.addParam("allowscriptaccess", "samedomain");
so.addParam("swliveconnect", "true");
so.write("fcmain");
else
if (document.getElementById && (version['major'] <
8)) {
var so = new SWFObject("fddmain.swf", "fddmain", "740",
"140", "9", "#FFFFFF");
so.addParam("quality", "high");
so.addParam("wmode", "opaque");
so.addParam("allowscale", "true");
so.addParam("allowscriptaccess", "samedomain");
so.addParam("swliveconnect", "true");
so.useExpressInstall('expressinstall.swf');
so.write("fctext");
// ]]>
</script>
I start by running "fp_6.0.65_activex.exe" to generate
"Flash.ocx", and copy "Flash.ocx" into
"C:\WINDOWS\system32\Macromed\Flash".
When I test with expressinstall.html, it shows that FP6 is
the current player and I get the Flash 9 updater prompt that goes
to ""
http://fpdownload.macromedia.com/pub/flashplayer/update/current/swf/autoUpdater.swf"
when I click yes.
So all is fine up to that point.
But when I get redirected to the Adobe Flash Player install
page the Flash movie that's supposed to run during the installation
doesn't appear, and so it never reports that the installation was
complete. The page simply loads without the install movie and
reports "Done" in the lower left corner. It never goes back to
index.php and reloads my flash movie (the way Firefox does).
In addition, the Adobe install page copies the following
files into "C:\WINDOWS\system32\Macromed\Flash"
"Flash9c.ocx", "FlashUtil9c.exe", "install.log",
"uninstall_activeX.exe". These appear to be the correct files. The
installation also leaves behind "Flash.ocx" which is from the
version 6.0.65 installation.
If I run expressinstall.html again it reports that there is
no Flash Player installed.
I've also removed this folder from the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Macromedia\FlashPlayer\SafeVersions.

Has anyone else run into this?

Back up all data if you haven’t already done so. Before proceeding, you must be sure you can restore your system to the state it’s in now.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
Drag or copy — do not type — the following line into the Terminal window, then press return:
sudo chflags -R 0 /Applications/Firefox.app
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning. If you don’t have a login password, you’ll need to set one before you can run the command.
Try the installation again. If it works, you can quit Terminal.
