Recently, I am helping one of my clients to upgrade the SharePoint 2010 to SharePoint 2013. They use the SharePoint Event Receiver Manager (2007/2010) to register and un-register the event receiver in their SharePoint 2010 environment (http://speventreceiverman.codeplex.com). The tool requires some updates to work with the SharePoint 2013 with Windows 2012.
Line 184 and 225: Update the directory to “”C:\Windows\Microsoft.NET\assembly\GAC_MSIL”
Line 465: string eventName = definition.Type.ToString();
