System. Runtime. InteropServices. COMException (0x80004005): Calls to COM components return an error HRESULT E_FAIL.

Hello:

I have some problem in Windows 7 x32 and x64 OS, When I use the same code in windows 10 OS, Its works fine without this exception.

I copy UIAtutomationCore.dll file from windows 7 OS to windows 10 OS. The UIAutomationCore.dll file is converted in windows 10 OS. (C:\UIA>TlbImp.exe UIAutomationCore.dll /out:Interop.UIAutomationCore.dll) . Mistakes do not happen every single time,
but occasionally.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.InteropServices;

using System.Text;

using System.Threading;

using Interop.UIAutomationCore;

namespace ConsoleTest

{

class Program

{

static IUIAutomationCondition propertyCondition;

static CUIAutomation _automation = new CUIAutomation();

static void Main(string[] args)

{

IUIAutomationCondition controlTypecondition = _automation.CreatePropertyCondition(UIA_PropertyIds.UIA_ControlTypePropertyId, UIA_ControlTypeIds.UIA_ButtonControlTypeId);

IUIAutomationCondition nameCondition = _automation.CreatePropertyCondition(UIA_PropertyIds.UIA_NamePropertyId, "ButtonName");

IUIAutomationCondition condition = _automation.CreateAndCondition(controlTypecondition, nameCondition);

try

{

IUIAutomationElement targetElement = _automation.GetRootElement().FindFirst(TreeScope.TreeScope_Subtree, nameCondition);

}

catch(COMException ex)

{

Console.WriteLine(ex.ToString());

}

Console.ReadKey();

}

}

}

The error message is as follows:

System. Runtime. InteropServices. COMException (0x80004005): Calls to COM components return an error HRESULT E_FAIL.

In Interop. UI Automation Core. IUI Automation Element. FindFirst (TreeScope scope, IUI Automation Condition)

Looking forward to your reply, thank you.

 

Registry Error - Windows Update - Error Code 0x80040154

Hello all,
I have an issue with my WIndows Updates, I am getting error code 0x80040154 and all the sites I checked did not help.

Here is my Windows Update log:
Got 9482F4B4-E343-43B6-B170-9A65BC822C77 redir SecondaryServiceAuth URL: 117cab2d-82b1-4b5a-a08c-4d62dbee7782""
CoCreateInstance Failed: hr = 0x80040154
Failed to retrieve SLS response data for service 117cab2d-82b1-4b5a-a08c-4d62dbee7782, error = 0x80040154
Caller Service Recovery failed to opt in to service 117cab2d-82b1-4b5a-a08c-4d62dbee7782, hr=0X80040154

Checked in the Registry and here is what is listed
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Services\Pending\117cab2d-82b1-4b5a-a08c-4d62dbee7782

I have tried everything to get it to the correct location without any luck.

SFC / DISM / ResetWUEeng / WinFixit / and the list goes on.

I also deleted it and broke my computer and could not restore it. Had to start all over again and still received the same error message.

Does anybody have any suggestions. Thanks.

 

Runtime Errors

Ok @FreeBooter. none of your suggestions worked. Still have the runtime error When ever I view the reliability history, under Maintenance.

Doing your last suggestion did nothing....did them separate and then rebooted.
