The problem might be that you try to run msiexec.exe and this exe is not in the cab file. See this question (be sure to scroll down to the incredibly helpful sample code posted by Roey 5 Aug 2009).
Try to either create a setup.exe that will run process msiexec.exe and install your msi or make an installer with a bootstrap setup.exe file and include both in the cab.
Also, you might want to read about non-admin activex installations.
Your activex dll has to be signed and your activeX should implement this interface
/// <summary>
/// Options supported for the IObjectSafety interface
/// </summary>
[Serializable]
[ComVisible(true)]
public enum ObjectSafetyOptions
{

I used advanced installer to create msi installer and I set dll registration. Advanced installer then generated all necessary registry keys.
In my test the final inf file was
[version]
signature="$CHICAGO$"
AdvancedINF=2.0
[Deployment]
InstallScope=user|machine
[Setup Hooks]
install=install
[install]
run="""%EXTRACT_DIR%
unmsi.exe""" """%EXTRACT_DIR%simpleactivex.msi"""
Please note the triple quotes. They are important.
I used this ddl
.Set DiskDirectoryTemplate=.
.Set CabinetNameTemplate=simpleactivex.cab
runmsi.exe
simpleactivex.msi
simpleactivex.inf
And I build cab using this commands
"c:Program Files (x86)Microsoft SDKsWindowsv7.0ABinsigntool.exe" sign /sha1 9A15DC8F51773C557BA2F75CF155F8CBD367A8E1 /tr http://tsa/tsa /d SimpleActiveX /du "http://yourcompany.com" /v runmsi.exe simpleactivex.msi
makecab /V3 /F make.ddl
"c:Program Files (x86)Microsoft SDKsWindowsv7.0ABinsigntool.exe" sign /sha1 9A15DC8F51773C557BA2F75CF155F8CBD367A8E1 /tr http://tsa/tsa /d simpleactivex /du "http://yourcompany.com" /v simpleactivex.cab
runmsi.exe is a dummy exe file that runs msiexec with given parameters. Alternatively you could use exe installer or bootstrap exe and msi installer. The important part to note is that IE will not allow to run anything outside the cab file. Therefore you have to do this hack.
When debugging I used this dummy html page
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >

<head>
<title>WebForm1</title>

<body style="margin-top: 0px; margin-left: 0px;">

<script language="javascript">

try

alert(document.SimpleActiveXCtrl.HelloWorld("hello"));
}
catch(Err)
{
alert(Err.description);
}
}
</script>
