title: Error with SqlSysClrTypes.msi when trying to install my application in C # and SQL Server
body: <p>I have an application developed in C# with SQL Server 2014 and I have the database included in the project.  </p>
  
  <p>When I install the program on my PC, I have no problems and the program works correctly.</p>
  
  <p>The error appears when trying to install the application on the client with Windows 7; the download of necessary files begins until at a moment it throws the error </p>
  
  <blockquote>
    <p>The setup has detected that the file c: //...route..//SqlsysClrTypes.msi has changed since it was initially published.</p>
  </blockquote>
  
  <p>and after this message the installation is canceled.  </p>
  
  <p>I found that maybe the error is due to the version of <code>SqlServer.Types.dll</code> is different from the one installed in the OS, in the program the version I have is 12.0.0.0 but I can not find the one in the OS. The path to verify the <code>SqlSysClrTypes</code> version in the windows registry is: </p>
  
  <pre><code>HKLM \ SOFTWARE \ Wow6432Node \ Microsoft \ Windows \ CurrentVersion \ Uninstall {718FFB65-F6E4-4D62-861F-ED10ED32C936}
  </code></pre>
  
  <p>I thought about updating the version I have in my application in some way, but I do not know how to do it.</p>
