I am almost certain that even the VMware knowledge base omits denoting exactly where the config.ini is supposed to be for Vmware Workstation 6.5 on 64-bit Windows 7 host. Several references to kb.vmware.com are provided by Toan Tran. What am I missing? By the way, I am trying to get rid of the "VMware Workstation has measured your CPU speed to be xxx MHz but Windows reports that it is xxx" message.
I ran across your question while looking for the same thing. I hope you've found the answer otherwise but here is the solution if not. This is for VMWare Workstation 6.5 on Windows 7 Pro x64.
1) Close Workstation.
2) Use a command prompt to change directory into: "c:\users\all users\vmware\vmware workstation\" 3) Enter "notepad config.ini"
4) Enter the following 3 lines (cpukHz is true Mhz x1000)
5) Save and exit. Then restart the VMWare Authorization Service.
You shouldn't see the error any more and the guest OS clock should be accurate.
I don't have a version of Windows 7 installed anywhere to test but this article seems to explain it.
