    text
    copied!<p>I am currently working on a C# WPF project which makes use of the MySQL.Data and System.Data.Sqlite dll as well as a couple of others.</p> <p>The project is a .Net 4 project which works without problems on my Development Machine. I create an MSI installer package and when I add the executable Visual Studio works out the dependencies and adds the required DLL's with the EXE. </p> <p>When I run the installer on my development machine everything works fine. However, when I copy the installer to a Blank Virtual machine with .Net Framework 3.5 and .Net Framework 4 installed the installer says that everything has installed successfully, when I look in the program files folder all the DLLs are there as well, but when I try to run the software the software doesn't load and .Net Runtime error is shown in the event viewer. </p> <p>The error is as follows</p> <blockquote> <p>Application: MySQLBackup.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception.

I also added try catch around <code>InitialiseComponent()</code> method which is executed on the first dialogue window that should load, but again the catch is never caught so I cannot see what is causing the error. </p> <p>How can I figure out what this problem is and fix it?</p>
