Solutions
Advanced Resolution

Step 1: Scan virus

If your computer infects malware or virus, it will report a trouble code 404 2004 cad 3.56 error to prevent malicious programs from executing. Virus or malware infection is one of the most frequent common viruses and starting a virus scan should be the first essay. If there is malware or virus on your PC, the error you occur is a signal of it. The correct and first reaction to that is running a full virus scan for computer system and personal files as soon as possible. If you already have installed antivirus app, then update it to the latest version and perform a virus scan.

Step 2: Repair registry

In some situations, the issue is caused by bad system maintenance and corrupted registry entries. Registry is damaged due to software installation or uninstallation, for example users install new apps over old ones without deleting or uninstall them properly. Many Windows users typically treat the system registry as SPOF (single point of failure), which indicates that OS associated with registry and registry corruption may cause system exceptions.

In order to clear up the error, you have to check registry entries and delete all superfluous and invalid entries, but for many users who are not computer experts, this will be a complex process. One incorrect operation may turn computer into inoperable, such as deletion of wrong input accidentally. If you are not a computer expert, you can attempt some third-party software which is able to scan and fix damaged registry automatically rather than fixing registry manually. A lot of such apps are available on the Internet, and most of them do equally well.

Step 3: Disable DEP (Data Execution Prevention)

Data execution prevention was originally introduced by Microsoft and used on Windows XP Service Pack 2 and later versions. It is a set of security features designed to prevent code execution from non-executable memory segments. It checks memory in order to protect computer againstkeep computer away from virus.

DEP has been enabled for both hardware and software components starting with Windows XP SP2. But some programs are still unable to be fully compatible with it. Some applications adopt a technique, usually called dynamic code generation, which doesn't mark these codes with an execute permission. As a result, this conflict leads to the problem. In addition, if software is developed without SafeSEH, it will cause trouble code 404 2004 cad 3.56 error when DEP is enabled on the computer.

If you get the error because of DEP, you can contact the developer of the software which cause the problem and ask whether they have a resolution. Alternatively, you can disable DEP for the software in question and this can be done by following steps:

  • Log in computer with Administrator account to make sure you have fully administrative rights.
  • If your computer is running Windows XP, click "Start" button and select "Run". Windows 7 user can press Windows + R keys. Type sysdm.cpl in Run box and click OK.
  • You can see System Prosperities window from which you need to click Advanced tab and then click Settings.
  • The "Performance Options" window will appear and please click "Data Execution Protection" tab. Select the option "Turn on DEP for all programs and services except those I select" and click "Add" button.
  • Browse files from the Open applet and find the exe files of the software which causes the error code. Select it and click "Open" button.
  • Click "Apply" and "OK" to make changes take effect.

Step 4: Remove bad RAM memory

A lot of times, a bad or incompatible RAM (Random Access Memory) lead to the issue. For instance, you've just added a new memory for your computer to improve performance; however, you start to receive error trouble code 404 2004 cad 3.56 from that time on. You can get rid of the problem by simply removing the memory and restarting computer to check whether the error has disappeared. If that works, retrieve the memory or replace it with one that is fully compatible with your computer.
Note: Before taking away RAM memory, you should turn off computer and remove all cables such as power, network, etc. If your PC is notebook, take out battery after shutting down computer.

Step 5: Update Internet Explorer 6.0

The error may appear in Microsoft Internet Explorer 6.0 when you try to open an HTML file or web page. Meanwhile, the IE may stop responding when the error occurs. This error appears specially when the HTML document or web page Internet Explorer 6.0 tries to open includes SPAN tags which were incorrectly closed. If the tags tag is not closed properly with tag, the access violation will happen.

With regard to solutions, Internet Explorer is outdated and current Windows 10 introduces Edge. You can install an updated version of Internet Explorer such as Internet Explorer 10 or use other free browsers such as Google Chrome, Mozilla Firefox, Opera, etc.
