title: Cannot install windows service
body: <p>I have created a very simple window service using visual studio 2010 and .NُET 4.0.</p>
  
  <p>This service has no functionality added from the default windows service project, other than an installer has been added.</p>
  
  <p>If I run "installutil.exe appName.exe" on my dev box or other windows 2008 R2 machines in our domain the windows service installs without issue.</p>
  
  <p>When I try to do this same thing on our customer site, it fails to install with the following error. </p>
  
  <pre><code>Microsoft (R) .NET Framework Installation utility Version 4.0.30319.1
  Copyright (c) Microsoft Corporation.  All rights reserved.
  
  Exception occurred while initializing the installation:
  System.IO.FileLoadException: Could not load file or assembly 'file:///C:\TestService\WindowsService1.exe' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515).
  </code></pre>
  
  <p>This solution has only 1 project and no dependencies added.</p>
  
  <p>I have tried it on multiple machines in our environment and two in our customers. The machines are all windows 2008 R2, both fresh installs. One machine has just .net 2.0 and .net 4.0. The other .net 2, 3, 3.5 and 4.</p>
  
  <p>I am a local admin on each of the machines.</p>
  
  <p>I have also tried the 64bit installer but get the following error, so I think the 32 bit one is the one to use.
  <code>System.BadImageFormatException</code></p>
  
  <p>Any guidance would be appreciated. Thanks.</p>
