ActiveX Download Problems

I did an ActiveX control for a web site and I can't get it to download properly. When a user tries to download the ActiveX he does not get an error but the ActiveX is not displayed, a red X is displayed in the top left corner of the control like an image that is not available. An html page is created in the Temporary internet files folder containing this information:

It works correctly on my computer. I have tried unregestering the associated files on my computer and when I go on the page it downloads the package and runs the ActiveX correctly.

Specifications:
-The control was done using VB6.
-The web page was done using .NET (this particular page is an aspx)
-The cab file was compiled using VB6's Package & Deployment Wizard
-The cab file is signed with Authenticode and so is the ocx inside
-The cab file is dependent on VB6 runtime files and another cab file

Here is how I reference the ActiveX:

<OBJECT id="gphEF" codeBase="http://dmweb/ActiveX/RPMViewGraph.cab#version=0,3,0,0" height="100%" width="100%" classid="clsid:0A88AF9A-7635-4AFF-A5D9-1E45E4FC7647" VIEWASTEXT>
<PARAM NAME="ScaleXInterval" VALUE="5">
<PARAM NAME="ScaleYInterval" VALUE="100">
</OBJECT>


What should I do so the user can download my control correctly?
