Thank you for your reply.   I will contain my posts on this subject to this thread.

My question which still has not been answered is that before this driver was only installed

when selected on VMWare tools installation.    If I did not select it, it was not installed on the guest.

Now it is mandatory.   Why?

I have tried to stop the installation on guests but it is still forced through.   Can you

provide a link where VMWare says that the vmci.sys on WIndows guests is now mandatory

and the reason why it is required?

Thank you for you help.
