I've built a WPF desktop application on .NET framework 4.5.1. It "usually" works fine, but, on certain machines, at runtime, a System.OutOfMemoryException when a WPF datagrid is going to be shown.

The stack trace reports:

An error of type System.OutOfMemoryException occurred.
       in System.Windows.Controls.ItemContainerGenerator.ContainerFromItem(Object item)
       in Microsoft.Windows.Controls.DataGrid.TryFindCell(Object item, DataGridColumn column)
       in Microsoft.Windows.Automation.Peers.DataGridCellItemAutomationPeer.get_OwningCellPeer()
       in Microsoft.Windows.Automation.Peers.DataGridCellItemAutomationPeer.IsEnabledCore()
       in System.Windows.Automation.Peers.AutomationPeer.UpdateSubtree()
       in System.Windows.Automation.Peers.AutomationPeer.UpdateSubtree()
       in System.Windows.Automation.Peers.AutomationPeer.UpdateSubtree()
       in System.Windows.Automation.Peers.AutomationPeer.UpdateSubtree()
       in System.Windows.Automation.Peers.AutomationPeer.UpdateSubtree()
       in System.Windows.Automation.Peers.AutomationPeer.UpdateSubtree()
       in System.Windows.ContextLayoutManager.fireAutomationEvents()
       in System.Windows.ContextLayoutManager.UpdateLayout()
       in System.Windows.ContextLayoutManager.UpdateLayoutCallback(Object arg)
       in System.Windows.Media.MediaContext.InvokeOnRenderCallback.DoWork()
       in System.Windows.Media.MediaContext.FireInvokeOnRenderCallbacks()
       in System.Windows.Media.MediaContext.RenderMessageHandlerCore(Object resizedCompositionTarget)
       in System.Windows.Media.MediaContext.RenderMessageHandler(Object resizedCompositionTarget)
       in System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs)
       in MS.Internal.Threading.ExceptionFilterHelper.TryCatchWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler)

Non-working machines are 32 bit, Windows 7, 2 GB of RAM, .NET framework 4.5.1.

I must say that the datagrid only displays few rows. I've been looking for similar errors on the web, but I couldn't find any suitable solution.

Any suggestion?

Thanks!

The problem turned out to be related to some missing privilege to the running account.

As soon as the user launched the executable by

right-click, Run as administrator

the problem disappeared.
