Author Posts December 17, 2018 at 1:10 pm #2386 WebmasterKeymaster When trying to start a VM in VMware Workstation, you may get this error: Could not get vmci driver version: The handle is invalid. You have an incorrect version of driver ‘vmci.sys’. Try reinstalling VMware Player. Module ‘DevicePowerOn’ power on failed. Failed to start the virtual machine. To fix that, firstly close down the VM, then open the VM’s VMX file in Notepad and find the line that says: vmci0.present = “TRUE” Change the “TRUE” to “FALSE”, save the VMX file and start the VM again. The VMCI driver error should now be fixed. Author Posts You must be logged in to reply to this topic.
