title: Publishing an application in Visual Studio 2010/2012
body: <p>I have a project built in Visual Studio 2010, with a copy of it built using Visual Studio 2012. Each time I click to publish the application and then email a zipped copy of the result(in either 2010 or 2012) I run into a problem where the application does not install at all with an error that the admin should be contacted or it installs and then a new copy of the same app does not(later on on the same machine). How do I fix this problem please? I have tried many of the suggested clickonce fixes on many threads already but I am wondering if there is a sure way to deal with this once and for all. </p>
