Each step below provides instructions and a link to a document, for performing the step and taking corrective action as necessary. The steps are ordered in the most appropriate sequence to isolate the issue and to identify the proper resolution. They are also ordered in the most appropriate sequence to minimize data loss. After each step, try installing Fusion again. It is recommended that you work through each troubleshooting step in order and do not skip a step.
To troubleshoot a failing installation:
  1. Ensure that your computer meets the System Requirements for Fusion. For details, see System requirements for VMware Fusion (2005196).
  2. Restart your Mac, and then try installing Fusion again.
  3. Check the MD5 sum value on the downloaded file. For more information, see Verifying Integrity of Downloads from VMware (1537).
  4. Make sure that you have enough disk space on your computer. The Fusion installation requires approximately 750 MB of free disk space. To determine the current free disk space, see the Managing Users and Permissions section of Investigating disk space in Mac OS X (1021932).
  5. Make sure that you have the necessary filesystem permissions to install Fusion:
    1. You need to be logged in as an administrator (or have an administrator's account information, when prompted). For details on how to determine if a certain account is an administrator account, see Common Mac OS operations that may be needed with VMware Fusion (1022113).
    2. Repair disk permissions on your Mac. For details, see this Apple Knowledge Base article Troubleshooting permissions issues in Mac OS X.
  6. Ensure that you are not missing any Mac system files. For details, see Verifying the health of an operating system (1003956).
  7. Ensure that your RAM is in good working order. For details, see Checking physical memory (RAM) on a Mac for VMware Fusion (1021740).
