When i start the virtual machine in VMware Workstation 8 i receive the following error:
You have an incorrect version of driver "vmci.sys". Try reinstalling VMware Workstation.
I unistall and reinstall VMware Workstation but still receive this error.
I've just hit this problem too when using windows 7 64 bit edition with workstation 7.0, I upgraded to workstation 8.0 to see if it fixed also tried repairing the install but no joy. “You have an incorrect version of driver vmci.sys”
Then I stumbled across some notes on someones blog which suggested the following
1. Open the vmx file related to the vm
2. Locate and change the following line to vmci0.present = “false”
Doing this allows me to power on my VMs but does not fix the issue fully. Not worked out how to do that yet.
the new buggy installer of version 8 has several problems with VMCI - on many systems the whole setup fails just because VMCI-install fails.
The situation gets worse because all default VMs have
vmci0.present = "true"
in the vmx - although only a very small number of users ever use it.
Workstation 8 installer can not really handle the installation or removal of the vmci driver.
Which one do you have ?
Anyway - disable it in the vmx for now if you are not interested in getting your hands dirty with registry and command line hacking
Step-1 Go to Virtual Machine folder where all VM stored, generally under "Document" folder
Step-2 Open each VM folder
Step-3 Open .vmx file with notepad++ editor
Step-4 Search "vmci"
Step-5 You will get a line: vmci0.present = "TRUE"
Step-6 Change TRUE to FALSE
Step-7 Save the file: Ctrl + S
Step-8 Repeat same steps for all the VMs
now you done!!
