title: Ankhsvn v2.4 could not be selected for Visual Studio 2013 source control plugin
body: <p>As the company, we were using Ankhsvn v2.3 with VS 2008. Lately, we have upgraded to VS2013 Community Edition, but we do not want to upgrade svn repo version so we upgraded to Ankhsvn v2.4. 
  Problem is, everything is okay in VS2012 both for Ankh2.3 and 2.4. However in VS2013, I cannot select it as the source control plugin (Anksvn 2.4) it gives me error saying that i must check the log file in appdata folder.
  Any ideas? is this a common issue? I have searched for it but most of the people upgraded their repos so they are using v2.5...</p>
  
  <p>Here is the log file by the way:</p>
