The ErrorLog element is optional. If it is not specified and one or more errors occur, they will be logged to the TWM application folder, C:\Document and Settings\<local user>\Local Settings\Application Data\TWM, with the default name of TWMBatchErrorLog.txt. The ErrorLog element, if specified, takes a single attribute called fileName, which is the name of the fully qualified file where errors will be logged to. If the path specified in the fileName is invalid, then any errors will be logged to the TWM application folder with the default batch file name.
