title: Application requires that assembly office version 12.0.0.0 be installed in GAC
body: <p>I have a .csproj that I want to publish to a clickonce server.
  When I publish the application from one development computer it works and the program can be started from the server without any problems.</p>
  
  <p>I download the same project from svn to another computer and try to publish it. That step kinda works, i guess, since the program is published successfully without any errors. </p>
  
  <p>But when I try to start the program from the server I get the error:
  Application requires that assembly office version 12.0.0.0 be installed in the Global Assembly Cache(GAC) first.</p>
  
  <p><strong>Update</strong>: (also posted info in comments). I am receiving this warning on both machines though I don't know how to solve. But it's probably the cause of the problem I guess: </p>
  
  <p>No way to resolve conflict between "office, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" and "office, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c". Choosing "office, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" arbitrarily.
  1>  Consider app.config remapping of assembly "office, Culture=neutral, PublicKeyToken=71e9bce111e9429c" from Version "12.0.0.0" [C:\Windows\assembly\GAC\office\12.0.0.0__71e9bce111e9429c\office.dll] to Version "14.0.0.0" [D:\Visual Studio\Visual Studio Tools for Office\PIA\Office14\office.dll] to solve conflict and get rid of warning.</p>
