.NET Framework 4.0.30319 error Solved

Question

Hello, What to do? Every time I use my PC, an error window opens: net framework 4.0.30319, I'm fed up with it, please help me fix it!!!!   Configuration: Windows 7 / Firefox 3.6.6

Hi Nika, I recommend uninstalling it because I had the same problem as many others, I think. In my opinion, it's bugged. If you want to know how to uninstall it, follow this guide:
In Firefox, go to Tools and open Add-ons, a window will open, then go to Extensions, click on .NET Framework and then on Uninstall.

I have the same problem on seven 64b
I have the version net framework 4 0 30319
To install framework 3.5
you need to enable the option "turn Windows features on or off" in the control panel

The process is simple:
Start button
Control Panel
Programs
Programs and Features
Turn Windows features on or off
Then check the right boxes for the framework

Thank you, Phil, for these explanations.
Like many, I have this issue with initializing the .NET FRAMEWORK.

The following window opens at least 2 times after starting my computer.
---------------------------
pthosttr.exe - .NET Framework Initialization Error
To run this application, you must first install one of the following versions of the .NET Framework: v4.0.30319
Contact your application publisher for instructions on obtaining the appropriate version of the .NET Framework.
---------------------------

When I follow Phil's procedure, after clicking on "Turn Windows features on or off," the corresponding window opens, but it is empty!
What should I do?
Knowing that I am really not an expert in IT...

Good evening,

Currently, the .NET framework 4.0 works without issues alongside version 3.5 SP1, at least when it was released.

However, to this day, it still contains errors with the 64Bit version of Windows 7.

It is therefore advised to keep an eye on Windows 7 updates while awaiting a fix.

(For your information, do not disable the .NET Framework as you will no longer be able to use certain applications or install others;)

I have an error message that keeps appearing, sometimes even two; what should I do to fix it?

Papy · Answer

I also had an error message after installing .NET Framework 4
I uninstalled it, way too many problems with this version.
To start, I disabled automatic updates to better control them.
To revert to my old configuration, I had to go to the Control Panel, select (Recovery), then choose (Open System Restore), go to (Search for affected programs), see (Choose a different restore point)
go back to .NET Framework 4, and restore it. The error display disappeared and my old version was reinstalled.

Blondain · Answer

Uninstall all versions of Netframework using the specific Krosoft utility, then reinstall all versions of "Netframework" as explained in "method 4", EXCEPT NETFRAMEWORK 4.
Link to the uninstaller and method 4 for reinstallation:
http://support.microsoft.com/kb/2507641/f
In addition to the uninstaller, also use everything that can be done through "add or remove programs" in the control panel.

So reinstall all versions in the order suggested by Krosoft, according to method 4, except for Netframework 4 and its "updates", as everything is severely bugged in this version.
Check the boxes in WU "do not offer me this update anymore" regarding anything related to Netframework 4.

I won't bore you with the numerous experiences that led me to this conclusion, with two examples, the resetting of WU (MicrosoftFixit50202.msi), the best being a generic response from Bacou like a standard email from Krosoft WU support.

And we'll see in 6 months or a year. A little joke, in the "method 4" for repairing Netframework, Krosoft conveniently forgets to mention that you need to reinstall Netframework 4.

In general conclusion:
Currently steering clear of Netframework 4 is the only solution to the problems, and spending energy to get out of this mess in the long term if you've been stuck with it.

Good luck, guys.

Anyway:
Playing on PC, with THE OBLIGATION TO OPEN FIFTEEN THOUSAND PORTS for His Lordship "STEAM" to work, is a big hello and goodbye to you,
if we have a minimum of security awareness.

So, there's really no rush for "Netframework 4".

We're either on gadgets or on consoles, depending on our perspectives.

Hello everyone, and sorry if this "Response" seems off-topic, but it will at least illustrate the mess that Framework can generate.

Here’s the display I get when, using the Firefox browser, after making a search request to Google with the two words expression bourrin, I click on the second link provided, which is:
bourrin: expressions with bourrin in the MEDIADICO dictionary
www.mediadico.com/dictionnaire/expression/bourrin/1

NB: if I enter the URL [www.mediadico.com/dictionnaire/expression/bourrin/1] directly in the address bar: no problem!
If it's from the second link displayed by Google, I get the following.

Server Error in '/' Application. Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. Stack Trace: [NullReferenceException: Object reference not set to an instance of an object.] Notrefamille.Utilitaires.Tracking.Enregistre_provenance_moteur() +6349 Mediadico.Web.Modules.TrackingModule.Application_BeginRequest(Object source, EventArgs e) in D:\Work\Mediadico\web\Mediadico.Web\Modules\TrackingModule.cs:28 System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +79 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +269

This fucking message is well referenced in the CrocSoft literature (2. Known Issues from the Readme of Microsoft.NET Framework 4) but it's in the 2.1 Installation chapter. ... and, to resolve the issue that .NET Framework 4 or ASP.NET, I don’t see myself modifying anything on my system disk, as suggested here:

To resolve this issue: At a command prompt, navigate to %windows%\Microsoft.Net\Framework\<latest version="">\ Execute the following command: aspnet_regiis.exe /iru</latest>

For those who have a problem with framework 47.0.3.... the solution is simple. Check if you have the Windows 7 Service Pack 1, that is the reason for your error.

Who can help me I'm launching my game and it says this: .net framework v4.0.30319 ...etc :'(

azryn · Answer

Good evening, personally, I've been searching for two days for why IE9 64 is lagging, and why I could no longer connect to Windows Live on the MSN page. The solution? A system restore to a point before this month's updates. Now, no more issues! Then I re-applied the updates while removing Framework 4. My PC has regained normal operating speed and no more problems with IE9 and Windows Live! It's crap, get rid of it!

Hello,

What is your operating system?

I am having a problem with Framework 3.5 SP1 & 4 on Microsoft Windows XP Home Edition SP3, I want to reinstall it but it keeps failing!!!

What should I do to repair Framework 3.5 SP1?

GVDD · Answer

This solution worked for me. Make sure it is compatible with your version of Windows (Control Panel/System and Security/System).

Download and install this version of the .NET Framework (or search for another if this one is not compatible): https://www.microsoft.com/en-us/download/details.aspx?id=49981

Normally after that, the message no longer appears and the application launches.
