Method 1: Uninstalling AVG (if applicable)
As it turns out, one of the most common scenarios that might end up causing this stop error code is a software conflict facilitated by AVG antivirus. This is confirmed by dozens of users that have successfully managed to make the 0x00000667 stop after uninstalling AVG from the Programs and Features menu. Note: Disabling the real-time protection is not enough since the same security rules will remain firmly in place. You should start by making sure that you’re using the latest version of AVG. According to affected users, this conflict can occur on both Windows 7 and Windows 10. If this scenario is applicable and you’re currently using AVG AV as the primary security suite on your operating system, follow the instructions below to uninstall it (and switch over to Windows Defender) in order to make the BSOD crashes to stop: In case this method was not applicable or the same error is still popping up even after uninstalling AVG, move down to the next method below.
Method 2: Using System Restore
If you only started seeing this issue recently, it’s likely that a recent software change is actually producing this error code due. If you have no suspects, your best choice at getting the issue fixed without having to do a clean install is to use the System Restore utility. Note: The culprit behind the 0x00000667 error code can occur for a variety of reasons including a bad Windows update, a botched driver installation, two conflicting 3rd party applications, etc. You can use the System Restore utility to use a previously created snapshot to return your computer to a previous state in time in which this stop error code is no longer occurring. But keep in mind that doing this will also revert any installed applications, installed Windows Update, driver, and even undo any custom settings that you have established since. In case you want to give this method a try, here are some step-by-step instructions on finding & using the best System Restore snapshot to fix the 0x00000667 error. Note: If you have the time to do this thoroughly, you should also remove any remnant files left behind by the uninstallation of the 3rd party AV. In case you already tried using System Restore to no avail or you were unable to find a viable restore snapshot created before the apparition of this error, move down to the next potential fix below.
Method 3: Disabling Hyper-V (if applicable)
If you’re using Nox player or a different Android-based emulator, it’s very possible that it’s conflicting with the Hyper-V service that’s enabled by default on your Windows computer. In this case, you should be able to prevent the 0x00000667 error from appearing again by accessing the Windows Features menu and disabling the Hyper-V Service before initiating a restart. Update: This type of conflict is also reported to occur between virtual machine software like Virtualbox and VMWare. This method was confirmed to work by a lot of affected users and it’s particularly known to be effective on Windows 10. If you find yourself in the same scenario, follow the instructions below to disable Hyper-V from the Windows Features menu: If you’re still encountering the same 0x00000667 error even though you’ve just disabled the Hyper-V features, move down to the next method below.
Method 4: Enabling Virtualization from BIOS or UEFI
If you’re encountering this problem when using some kind of application that uses virtualization technology (Android Studio, Nox, VMWare, VirtualBox, etc.) it’s possible to encounter the 0x00000667 error code because SVM (Secure Virtual Machine) or Intel’s equivalent (Intel VT-X / Intel Virtualization) is disabled in your BIOS or UEFI settings. If this scenario is applicable, you should be able to fix the problem by accessing your BIOS or UEFI settings and enabling the virtualization technology – This will allow the applications that rely on this technology to run normally without encountering the same 0x00000667 error code. Keep in mind that enabling SVM or VT-X is a different procedure depending on the motherboard manufacturer. However, the exact steps you need to perform ar similar on every BIOS or UEFI version: Start by pressing the Setup key immediately after you boot up your computer. Once you’re inside the BIOS or UEFI settings of your motherboard, look for an option SVM Mode or Inter Virtualization (depending on your CPU manufacturer) and enable it before saving the changes. Note: Typically, you can find this option inside the Advanced / Expert tab under CPU Configuration / Virtualization. Once the virtualization technology has been enabled, save the changes before restarting your computer and allowing it to boot normally. After your computer boots back up, repeat the action that was previously causing the 0x00000667 error. In case the issue is still not resolved, move down to the next potential fix below.
Method 5: Installing Intel Haxm (if applicable)
If you’re encountering this stop error code while using an Android Emulator like BlueStacks or Nox when testing apps that are still in development mode, you might be able to fix the problem by installing Intel Xaxm (only applicable if your PC is using Intel’s Virtualization technology – Intel VT). In this case, you should be able to fix the problem by downloading and installing the latest official Intel Haxm directly or using SDK Manager. If this scenario is applicable, follow the instructions below to fix the 0x00000667 error by installing the Standalone Intel HAXM on Windows. Here’s what you need to do: In case the same issue is still occurring, move down to the next potential fix below.
Method 6: Re-Registering Windows Installer
If you’re encountering the 0x00000667 error coupled with the ‘Invalid command-line argument’ message when attempting to install a new program using Windows Installer or when using a component Windows Installer SDK, you might be able to fix the problem by temporarily unregistering the Windows Installer component from an elevated CMD prompt before registering it again. Several affected users that found themselves in a similar scenario have confirmed that the procedure below has finally allowed them to fix the problem. Here’s what you need to do: In case the same 0x00000667 error is still occurring, move down to the next potential fix below.
Method 7: Enabling the Windows Installer service
If none of the methods above have worked in your case and you’re experiencing this type of error when doing something that’s handled by a Windows installer, you should also take the time to ensure that the main service behind the Windows installer is running uninterrupted. Several affected users that were previously dealing with the same 0x00000667 error have confirmed that they managed to fix the issue by accessing the Servicing screen and noticing that the Windows Installer service was disabled. They managed to fix it by forcing the services to start before repeating the operation that was causing the error. If this scenario is applicable to your scenario, follow the instructions below to re-configure the Windows Installer service to be on-call whenever it’s needed:
