No error detail when using VMPrep

When using VMPrep to setup a VM for use in a Lab Management system I got the error cross at the bottom of the dialog

Not too much help, usually there is a link to the log file or a message.

If you look in the log file in c:\user\[name]\Appdata\Roaming\LMInstaller.txt you see that the path to the Patches folder is invalid.

This is fixed by editing the VMPrepTool\VMPrepToolLibrary\Applications.XML file and correcting the path (which I had made a typo in)
