# Driver Error : C035001E

Most of the time this error is caused by your system not having virtualization on or your system not having Hyper-V off. The following list of fixes should make this error disappear when loading.

1. **Turn on Virtualization in BIOS (C035001E Error)**\\

Firstly, let's check if you have Virtualization on already. You can do so by opening Task Manager, then opening the performance tab.

* If it says Virtualization's disabled, then head to your BIOS to turn it on. If it is enabled, then you can go ahead and skip to the next step.
  * ## Virtualization for Intel Users:

    Once in your BIOS settings, head over to the advanced tab and select CPU configuration.&#x20;

    From there, go to Intel Virtualization Technology and enabled it. Save the changes and exit.

    Your BIOS settings may differ depending on your manufacturer.

* ## Virtualization for AMD Users:

  Once in your BIOS settings, head over to the advanced tab and select CPU configuration.&#x20;

  From there, go to SVM Mode and enabled it. Save changes and exit.

  Your BIOS settings may differ depending on your manufacturer.&#x20;

2. **Turn off Hyper-V in Windows (C035001E Error)**

* In order to turn off Hyper-V in Windows start by opening a Windows Powershell as Admin. This can be done by typing powershell into your windows search, and pressing "Run as administrator" which can be found beside it.
* enter seperately:\
  `bcdedit /set hypervisorlaunchtype off`\
  `Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All`
* Getting an error that says "Disable-WindowsOptionalFeature : Feature name Microsoft-Hyper-V-All is unknown." is completely normal. After this, restart your PC for the changes to take affect.

3. **Turn off antivirus software**

* The easiest way to do this is to download a program named "DControl" and using it to fully disable Windows Defender. A link to that program can be found here: <https://www.sordum.org/9480/defender-control-v2-1/> - Password: sordum (if needed)
* If you cannot disable Windows Defender with DControl then do it manually here. Therefore head to Windows Security. Then click on Virus & Threat Protection. Below Virus & Threat Protection Settings, click on Manage Settings. Then turn off Real-Time Protection.
* If you are on Windows 11 22H2, we need to turn off Core Isolation too. Head back to the main menu of Windows Security and click on Device Security. Click Core Isolation Details, then turn off Memory Integrity. Restart your PC after making these changes.
* Now you have to make sure you don't have any 3rd Party Antivirus software active. Press your windows key, type "Add or remove program" and within that list of programs, delete any that are third-party antivirus software. Here's a list of them - <https://tinyurl.com/yyasj83u>

4. Disable the Vulnerable Driver Blocklist (Only Required for Windows 11 22H2)

* Start by opening a Command Prompt as Admin. Once open, copy and paste the following line of code, then type "y" or "yes" to confirm the changes:                                                                   `reg add HKLM\SYSTEM\CurrentControlSet\Control\CI\Config /v VulnerableDriverBlocklistEnable /t REG_DWORD /d 0x000000`
* It may ask you to overwrite/create a new registry key, which you can also confirm by typing "y" or "yes" to confirm that. Restart your PC after you are finished.\\
