title: deploy .net 4.0 wpf application problem
body: <p>I been working on a application that I am planing on distributing. For some reason I am not able to install it on other computers. first let me show you my deployment settings maybe I am doing something wrong in there (I left all the defaults).</p>
  
  <h2>Deployment settings:</h2>

  <p>So far everything looks great! Let me show you what happens when I try installing this app on several computers:</p>
  
  <p>.</p>
  
  <h2>Computer 1: (Running windows 7 with Service Pack 1)</h2>
  
  <p>application installs in a matter of seconds and it works fine. 
  I am able to uninstall it as:

  <p>THE APPLICATION WORKS GREAT!</p>
  
  <p>.</p>
  
  <h2>Computer 2: (Running windows vista with service pack)</h2>
  
  <p>IT DOES NOT INSTALL:</p>

  <p>when I click on install I get the following error:</p>
  
  <p><img src="https://i.stack.imgur.com/pzguv.png" alt="enter image description here"></p>
  
  <p>so as you can see I was not able to install it on that machine. I tried uninstalling it then installing it again and I get the same problem. </p>
  
  <p>.</p>
  
  <p>.</p>
  
  <h2>computer 3: (running windows xp with service pack 2)</h2>
  
  <p>when I ran the setup.exe file it took a while to download and install whatever requirements it needed. It took 1 hour to install what I believe was the:</p>
  
  <p><img src="https://i.stack.imgur.com/UIHUj.png" alt="enter image description here"></p>
  
  <p>and when that part finished at the end I got an error saying: "you do not have enough disk space" and I have 50GB of free disk space on my c drive. </p>
  
  <p>SO IT DID NOT WORK WITH THIS COMPUTER EATHER.</p>
  
  <p>.</p>
  
  <p>.</p>
  
  <h2>Computer 4: (windows xp with service pack 2)</h2>
  
  <p>I get the following error:</p>

  <h2>why is it so difficult to deploy an application. this application works great in all the computers that have visual studio installed. Should I try to downgrade to .Net 3.0 or maybe .Net 2.0?</h2>
  
  <hr>
  
  <h2>Edit</h2>
  
  <p>Could this be because I might not be able to publish applications? I got visual studio for free because my university gave it to me. I know there are student versions where you can try and also that they expire every six months. I been using visual studio ultimate edition for about 1 year know and every time I launch visual studio it does NOT say for evaluation purposes only like on my laptop. My splash screen actually comes out as:</p>
