Infopath task edit form for SharePoint 2010 sequential Workflow

Question

I have a SharePoint 2010 sequential approval workflow in Visual Studio 2010. I am trying to hookup infopath form so users can indicate their approval or rejection by clicking on approve or reject button on the infopath form.
I created the form, published it and imported into my workflow. After reading some posts I added the following feature xml file so my VendorRegistrationApproval.xsn file is deployed to the central admin that I can then hookup to my workflow.  


<Feature xmlns="http://schemas.microsoft.com/sharepoint/" ReceiverAssembly="Microsoft.Office.Workflow.Feature, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" ReceiverClass="Microsoft.Office.Workflow.Feature.WorkflowFeatureReceiver" Title="MPS.Solutions.Facts.WF Supplier RFQ" Description="SharePoint feature to create Word documents from material request spreadsheet utilizaing Open XML technology." Id="d5afb3c6-1748-4872-87a5-506e8fdca0bd" Scope="Site">
  <Properties>
    <Property Key="GloballyAvailable" Value="true" />
    <Property Key="RegisterForms" Value="VendorRegistration\*.xsn" />
  </Properties>
  <ElementManifests>
    <ElementManifest Location="MaterialRFQ\Elements.xml" />
    <ElementManifest Location="VendorRegistration\Elements.xml" />
    <ElementFile Location="VendorRegistrationApproval.xsn" />
  </ElementManifests>
</Feature>

Everything deploy fines but I don't see my form in the Central Admin under Manage Form Templates. I have search around and tried various other options but with no success. I am hoping someone here has done it successfully and can save me some grief.

Thanks,
