.NET Framework error: Root Element Missing - WKB16351

SYMPTOMS

• When starting MS Console, a "Root Element Missing" .NET error message appears

• The Details tab of the error message reads "System.Xml.XmlException: Root element is missing."

ENVIRONMENT

• MassLynx MS console
• ACQUITY console

CAUSE

There is a problem with the ACQUITYSettings.xml file. The ACQUITYSettings.xml file essentially controls which modules are displayed within the MS Console window, and this file can occasionally be corrupt.

FIX or WORKAROUND

1. Remove all the modules from the configurator and configure again. If this does not work, proceed to step 2.
2. Run StopACQUITYProcesses.cmd from C:\Program Files (x86)\Waters Instruments\Bin.
3. Go to the folder C:\Program Files (x86)\Waters Instruments\Settings and rename or delete the current ACQUITYSettings.xml file
4. Reopen MassLynx and the MS Console. The ACQUITYSettings.xml file is re-created and the console window should now show correctly.

ADDITIONAL INFORMATION

Do not reinstall .NET Framework.

When you see a .NET Framework error coming from the console, it almost always signifies that the console (which runs on Microsoft's .NET Framework programming tools) has a problem, not a problem with .NET Framework itself.
