Fatal error meaning. Fatal error in AutoCAD Unhandled e0434352h Exception at - how to fix

This article will describe several ways to solve problems associated with the AutoCAD program.

We will talk about errors that appear when starting AutoCAD, when saving a drawing, or even when trying to print a document on a printer connected over the network.

Namely, about an error leading to emergency closure of the program:

Fatal error unhandled e06d7363h exception at fd76bccdh

FATAL ERROR: Unhandled e0434f4dh Exception at 7c81eb33h

Unhandled exception at address 7c81eb33h

They look a little different, but they are equally infuriating.

These error messages indicate that the program was damaged during installation. For example, during installation, some files were blocked by an antivirus, Windows Defender, or a digital signature verification service. Therefore, it is recommended to disable the antivirus when installing the program and close all other applications that may interfere with the installation process.

Now let's move on to actually solving the problem.

Method 1

In the first case, consider the error that occurs when printing a document on a network printer:

Fatal error unhandled e06d7363hexception at fd76bccdh

To get rid of it, you can try deleting the folders:

C:\Users\USRNAME\AppData\Roaming\Autodesk and C:\Users\USRNAME\AppData\Local\Autodesk

And reinstall AutoCAD.

Method 2

The next thing that can help fix this error is reinstalling the software:

NetFramework 1.1

The best thing to do is to remove all versions of NetFramework from the system and re-run the AutoCAD installation. During installation, the installer itself will reinstall NetFramework to a more suitable AutoCAD.

Method 3

At the beginning of the article it was already mentioned that during installation the installer may be interfered with by the digital signature verification service. So you will need to turn it off.

For this:

Open the Run dialog box, you can run it either from Start or by pressing a keyboard shortcut WIn + R.
Enter the command acsignoptand press Enter.

3. In the “Digital signature verification settings” window that appears, uncheck the box next to “Verify digital signatures and display special icons.”

4. Click OK to close the window. Completely uninstall and reinstall AutoCAD.

Check functionality. If the error still appears, then move on to the next method.

Method 4

In the fourth method, you will need to change a couple of values in the registry.

Launch Registry Editor.
Go to the following path: HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R18.0\ACAD-8000:409\WebServices\CommunicationCenter

Note! The path may be slightly different, namely the meaning R18.0 may be different depending on the AutoCAD version. For example R19.0, there is nothing wrong with that, feel free to move on.

4. Change the values of both keys to 00000000 (eight zeros).

Note! To edit the registry you need administrator rights.

“Fatal” - how is that? We often hear this word in different contexts, so its meaning is not always clear. Today we will clarify the meaning of the adverb and some phrases with it.

"Fatum" is fate

Indeed, from the Latin “fatum” is fate. Therefore, you can easily establish that fatal is:

Something mysterious, fatally determining a person’s life.
Something that suggests tragedy, perhaps death.

But don’t be afraid, most often we are not talking about death, but rather about predestination. For example, you can hear from commentators of team sports matches: “This mistake by the goalkeeper turned out to be fatal for the team.” After all, the audience understands: the goalkeeper did not cause a fatal illness for all his teammates, and they did not die after the match. In this case, the goalkeeper's mistake is fatal, because it predetermined the result of the match and turned out to be fateful. "Fatal" is something that cannot have a happy ending.

Fatalism and voluntarism

Surprisingly, what is associated with fate is not endowed with a positive meaning by a person.

There are mutually exclusive systems - fatalism and voluntarism. With fatalism, everything is clear - this is a worldview that believes: there is no freedom in the world, and everything is subordinated to a single plan of fate. Moreover, be that as it may, a fatalist is not necessarily a pessimist. These are people who believe in fate, who believe that they will definitely be lucky, at least some of them. Another thing is that they are rarely lucky, but that doesn’t matter. In most cases, fatalism involves a fair amount of pessimism and doom. People usually remember fatalism when a person is rolling down an inclined plane.

What about “voluntarism”? The term is familiar to Soviet and Russian viewers from the film “Prisoner of the Caucasus” by L. Gaidai. But few people know what it means. And the concept presupposes the following belief: the main driving force in the world is the freedom of man or God (or what replaces Him). And I would like to say that voluntarism, in contrast to fatalism, is optimistic, but, remembering the thinkers who adhered to this doctrine (F. Nietzsche, A. Schopenhauer), somehow my tongue cannot be turned. The main difference between fatalism and voluntarism lies in the following: some believe that there is no freedom, while others believe that there is nothing but freedom. One way or another, “fatal” is something that will definitely not end well for a person.

Martin Eden as an example of tragic fate

Jack London's novel is an eternal work; it tells the story of a man's battle with fate and life. The bad thing about this work is that the author had a certain ideological attitude: love is the main driving force in the world. And while the hero of London thought that Ruth loved him, he overcame himself and developed. After all, Martin Eden is a genius. But as soon as the main character realized that Ruth was a dummy, he immediately wilted. For those who have not read, we will not reveal all the cards, but let’s say: the meeting with Ruth predetermined the fatal outcome (what this means is clear from the context, and if it is not clear, then read Jack London) of the fate of Martin Eden.

The author's fateful mistake

Jack London is an eternal author, that is, he will be read as long as the English language and people capable of translating from it exist, but he also made a mistake, which cost his hero dearly. The astute reader will understand what is at stake. Jack London believed: the most important thing in life is love, and when a person is deprived of love, then he has no reason to live. Martin Eden became a victim of precisely this attitude. And this quite fits the definition of “fatal mistake” - this is what predetermined the fate of the hero, played a cruel joke on him. Jack London's system-forming belief about love devalued Martin Eden's entire struggle for the right to be himself.

A fatal error may appear when starting AutoCAD. It blocks the start of work and you cannot use the program to create drawings.

In this article we will look at the reasons for its occurrence and suggest ways to eliminate this error.

Fatal access error

If, when you launch AutoCAD, you see a window like the one shown in the screenshot, you need to run the program as an administrator if you are working under a user account without administrator rights.

Right-click the program shortcut and click “Run as administrator.”

Fatal error when locking system files

A fatal error may look different.

If you see this window in front of you, it means that the program was installed incorrectly, or the system files were blocked by the antivirus.

There are several ways to solve this problem.

1. Delete the folders located at: C:\Users\USRNAME\AppData\Roaming\Autodesk and C:\Users\USRNAME\AppData\Local\Autodesk. After this, reinstall the program.

2. Press Win+R and type “acsignopt” at the command line. In the window that opens, uncheck the “Verify digital signatures and display special icons” checkbox. The fact is that the digital signature service may block the installation of the program.

3. Press Win+R and type “regedit” at the command line.

Find the branch HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R21.0\ACAD-0001:419\WebServices\CommunicationCenter.

The folder names "R21.0" and "ACAD-0001:419" may differ in your version. There is no fundamental difference in content; choose the folder that is displayed in your registry (for example, R19.0, not R21.0).

Select the “LastUpdateTimeHiWord” file and, calling the context menu, click “Edit”.

In the “value” field, enter eight zeros (as in the screenshot).

Do the same for the "LastUpdateTimeLoWord" file.

The cause of the Unhandled e0434352h Exception error in the video adapter

When working with the AutoCAD program, the computer needs to work with 3D graphics, and for this you need a fairly powerful graphics adapter. If your computer was purchased several years ago, it is possible that it does not meet the parameters required to run the program. To fix the situation, you can try:

Reasons for the appearance of Unhandled e0434352h Exception in the registry file

If the error occurs when you open the File tab in AutoCAD, then the problem is due to a problem file in the Microsoft dynamic link library (dll). To solve this problem:

Open the “Registry Editor” by right-clicking on the “My Computer” icon.
Next, go to the section HKEY_CURRENT_USER/Software/Autodesk/AutoCAD/R18.0/ACAD-8000:409/WeServices/CommunicationCenter.
Change the value of the LastUpdateTimeHiWord key to 8 zeros.
We change the similar LastUpdateTimeLoWord key to the same value.
Restart your computer.

Insufficient RAM to run AutoCAD

With standard computer settings (if no one has changed them), the application is allocated a certain amount of RAM to work in the system. 2 GB is a common limitation for OS with 32-bit architecture. If this line is crossed, Windows automatically shuts down running programs. Therefore, when working with the program, it is necessary, if possible, not to open any programs in parallel that may occupy a large amount of virtual memory.

The reason is the digital signature service is not working properly

Unhandled error e0434352h Exception appears when requesting a digital signature for an application. To disable this feature to prevent the error from appearing in the future, you need to:

Go to the Start menu, then click Run and type acsignopt in the window.
In the “Digital signature verification settings” window that opens, you need to uncheck the “Verify digital signatures” box.
After these steps, restart your computer.
