3.5 - 4.5 Upgrade. ActiveX fails with 'The server or proxy not found'

We have upgraded our Image Uploader from 3.5 to 4.5

In order to facilitate this I have overwritten the iuembed.js and copied the cab & jar files over. The only change to the php page calling the script was to update the following lines:

iu.activeXControlCodeBase = "/ImageUploader3.cab";
iu.activeXControlVersion = "3,5,180,0";

//For Java applet we specify only directory with JAR files
iu.javaAppletCodeBase = "/";
iu.javaAppletCached = true;
iu.javaAppletVersion = "1.1.60.0";

becomes

iu.activeXControlCodeBase = "/ImageUploader4.cab";
iu.activeXControlVersion = "4,5,4,0";

//For Java applet we specify only directory with JAR files
iu.javaAppletCodeBase = "/";
iu.javaAppletCached = true;
iu.javaAppletVersion = "2.5.4.0";

The java applet in Firefox works fine, but the ActiveX fails with a pop up 'The server or proxy not found'

ShowDebugWindow is set to true, but this pops up a 404 error

Any ideas would be greatly appreciated

Thank you for your less than useful response.

For anyone else who has this issue, I fixed it by specifying the http_host in the action parameter:

$action = 'http://' . $_SERVER['HTTP_HOST'] . '/multiimage_upload.php';

called by

iu.addParam("Action","{$action}" );

In 3.5 we only needed to specify the page required, not the server:

iu.addParam("Action","/multiimage_upload.php" );

This fails in 4.5

Java works fine ( as I said in my first post)

Any progress on the fix for this?

Thanks,
