title: How to move a ClickOnce deployment package
body: <p>I have a collection of ClickOnce packages in a publish folder on a network drive and need to move them all to another server (our DR machine).  </p>
  
  <p>After copy/pasting the whole directory and running the setups on the new machine I get an error message stating that it cannot find the old path:</p>
  
  <blockquote>
    <p>Activation of
    ...MyClickOnceApp.application resulted
    in exception. Following failure
    messages were detected:</p>
    
    <p>+ Downloading file://oldMachine/c$/MyClickOnceApp.application did not succeed.</p>
    
    <p>+ Could not find a part of the path '\\oldMachine\c$\MyClickOnceApp.application'.</p>
  </blockquote>
  
  <p>Once I change the installation <a href="http://en.wikipedia.org/wiki/Uniform_Resource_Locator" rel="nofollow noreferrer">URL</a> to point at my new machine, I get another error:</p>
  
  <blockquote>
    <p>Manifest XML signature is not valid.</p>
    
    <p>+ The digital signature of the object did not verify.</p>
  </blockquote>
  
  <p>I've tried using <a href="http://msdn.microsoft.com/en-us/library/xhctdw55.aspx" rel="nofollow noreferrer">MageUI.exe</a>, to modify the deployment URL, but it asks for a certificate, which I don't have.</p>
  
  <p>What am I doing wrong and how do I successfully move published ClickOnce packages?</p>
