Installing VMware Workstation 9.0 on Windows 8 RTM

I recently ran into an issue where VMware Workstation 9.0.1 refused to install, with the management port configured to the default of port 443. It was complaining that another process was using that port already. I broke out [cci]netstat -aon[/cci] and discovered that wwahost.exe was listening on port 443. It turns out that [cci]wwahost.exe[/cci] is a new Windows 8 process that is used to launch Windows 8 “modern UI” applications, or something along those lines.

Although rebooting your computer will probably fix the problem, you can just Alt + Tab over to any Metro UI applications and close them by hitting Alt + F4. Once you’ve closed all of your Metro “modern” UI apps (don’t forget Metro-style Control Panel settings screens, and similar), you should be able to proceed with the installation of VMware Workstation.
