Resolution
After installing Windows 7 SP1 or Windows 2008 R2 SP1 on a 64bit host, you may experience this issue while trying to start a virtual machine. This issue is resolved by Workstation 7.1.4. You can download the latest version of Workstation from our Download Center. This issue occurs because SP 1 changes the way in which Windows handles memory management. For more information about the changes in SP 1, see Documentation for Windows 7 and Windows Server 2008 R2 Service Pack 1 (KB976932). If you cannot install the latest version of Workstation, you have other alternatives: You can resolve this issue by uninstalling SP1. For more information, see How to uninstall Windows 7 Service Pack 1 (SP1) .Note: The preceding links were correct as of March 22, 2011. If you find the link is broken, provide feedback and a VMware employee will update the link. To workaround this issue, you can add a setting to the config file to restrict Workstation to using a percentage of the host's available RAM: Shut down all running virtual machines and exit Workstation. Open the config.ini file located at C:\ProgramData\VMware\VMware Workstation. Add this line to the file:vmmon.disableHostParameters = TRUE Save and close the file. Restart Windows. This ensures that the virtual machine uses only 75% of the host memory.
