When VMware Workstation 8 is installed on a MS Windows 7 x64 machine, and you’ll update de software to the latest version, the installation can fail with error 25028 in vmwarevmcisocket64.msi.
The installation first uninstalls the old version, then reboots the machine and after you’re loggedin, the installation of the new version continues. When anwsered a couple of questions, the installation exits with error 25028.
This problem is quite simple to solve;
First disable your antivirus-program (in my case MS security Essentials).
Second go to C:\Users\username\AppData\Local\VMware\vmware-download-XXXX\cdstmp-ws-windows_8.X.X_XXXXXX\
Now find and right-click the application “VMware-workstation-8.X.X-XXXXXX.exe” and select “Run as Administrator”.
The installation will now complete succesfully.
Note: Your original installation-volume has to be present in order to do the installation (in my case drive E: which contained the original workstation installation).
