How to Fix the "VMware Workstation Error: Unable to Open Kernel Device ‘\\.\VMCIDev\VMX’" Error
So, what's triggering this error? Thankfully, the error message itself gives us enough information to pinpoint the cause.
The "VMCI" part of the error stands for "Virtual Machine Communication Interface." It provides efficient and fast communication between a virtual machine and the host operating system, and between two or more virtual machines on the same host. The VMCI is present in all virtual machine providers like VMWare, VirtualBox, and Hyper-V.
As such, to fix the problem, we have to tackle the VMCI. So, let's get into fixing this error.
1. Fixing the VCMI Error
To solve this error, you need to edit the VMX file of the virtual machine that pops the error. A VMX file contains the hard disk, memory, and processor limit settings of the virtual machine.
- Locate the folder of the virtual machine.
- Search for the VMX file. It doesn't necessarily need to end with the VMX suffix. Search for an icon that looks like three white pages.
- Open the file with Notepad or any text editor.
- Search for the line with vmci0.present.
- Change the value from "TRUE" to "FALSE".
- Save and close the file.
- Restart your computer.
Your virtual machine should run without hitches now.
2. Uninstall and Reinstall the VMware Workstation
If the first fix doesn't work, uninstall the VMWare workstation program and reinstall it. This would reset it, and then you can use your virtual machines again. Here's how to uninstall programs on Windows 10 and some different ways to uninstall software in Windows 11.
The VMware Workstation Error Is Now Fixed
Now you know how to fix this VMWare error. We hope that the steps above have completely solved your problem and that your virtual machines are up and running. However, if the error persists, you could try contacting the VMWare support team.
How to Fix "This PC Can't Run Windows 11" Error on VMware Workstation
Windows 11 is a demanding OS, so here's how to get it to play nice with your VMware Workstation.
Windows 11 is a free upgrade for Windows 10 users, but it does come with hardware limitations. As a result, when you try to install Windows 11 as a guest on your VMware workstation, you may encounter the "this PC can’t run Windows 11" error.
Here we show you how to bypass this error and install Windows 11 on your VMware Workstation Player, Pro, and Fusion.
What Causes the "This PC Can’t Run Windows 11" Error on VMware Workstation?
To install Windows 11, your PC must meet the TPM 2.0 and secure boot requirements. However, even if you have a compatible PC, VMware Workstation Player doesn’t support this feature by default, resulting in an error.

1. How to Enable TPM 2.0 on a Virtual Machine (VMware Workstation Pro)
If you use VMware Workstation Pro, you can encrypt your virtual machine and then add a virtual Trusted Platform Module (TPM) to fix the error.
If you use VMware Workstation Player, skip to the next method involving a registry hack and vmx file modification.
To encrypt and add TPM to your virtual machine:
- Launch VMware Workstation Pro. Create a new virtual machine if you don’t have one already.
- Then, select and right-click on your virtual machine and choose Settings.
- In the Settings window, open the Options tab.
- In the left pane, select the Access Control tab.
- In the right pane, click on the Encrypt button.
- Enter an encryption password and repeat it to confirm. Save the encryption password in a safe location as you need it to access the virtual machine.
- Click the Encrypt button and wait for the encryption process to complete.
- Once done, click OK to save the changes.
- Now you can add TPM to your virtual machine. To do this, right-click on your encrypted virtual machine and select Settings.
- In the Hardware tab, click the Add button.
- Select Trusted Platform Module in the Hardware Type window.
- Click the Finish button to add virtual TPM to your virtual machine.
- In the Settings window, Trusted Platform Module will show Present in the Summary column.
- Click OK to save the changes.
Now you can go ahead and install Windows 11 on VMware Workstation Pro without the system requirement error.
2. Edit the VMX File to Add VTPM in VMware Workstation
The easiest way to fix the PC can’t run Windows 11 error is to edit your virtual machine's vmx file and add the VTPM (Virtual Trusted Platform Module). This method works on all the versions of VMware Workstation, including Pro, Player and Fusion.
To use the software feature by editing the vmx file:
- Launch VMware Workstation. Create a new virtual amchine if you don’t have one already. Also, power off any running virtual machine.
- Right-click on your virtual machine and select Settings.
- Open the Options tab in the Settings window.
- In the right pane, locate Working directory. This is where the vmx file for your virtual machine is located. So, copy the working directory path to your clipboard.
- Click OK to close the Settings window.
- Press Win + E to open File Explorer and navigate to the working directory path. The path may vary depending on where you have chosen to install the virtual machine. The default working directory path looks something like this C:\Users\UserName\Documents\Virtual Machines\Windows 10 and later x64
- In the Windows 10 and later x64 folder, locate the Windows 10 and later x64.vmx file.
- Right-click on the .vmx file, select Open With > Notepad. You can also use other text editors such as Notepad++.
- When the file opens in Notepad, add the following line in the end: managedVM.autoAddVTPM = "software"
- Press Ctrl + S to save the file and close Notepad.
- Once the file is modified, restart VMware Workstation, Fusion, or Player.
- After restart, power on your virtual machine and continue with the Windows 11 setup. You should be able to bypass the TPM check and complete the setup.
