Grapher Installation Error: "Overlapped I/O operation in progress."

If you are attempting to install Grapher and the install fails with an "Overlapped I/O operation is in progress." error message, it is most likely due to a Windows error caused by Microsoft security update KB2918614.


Microsoft recommends applying a hotfix released to address this issue. Refer to "The profile for the user is a temporary profile" error when you install a MSI package in Windows for the Microsoft hotfix.


Another solution is to remove the Windows update that triggered the error. To do this:

  1. Click the Windows Start button and select Control Panel.
  2. Click the Uninstall a program option.
  3. On the left side, click View installed updates.
  4. In the search box at the top-right search for KB2918614.
  5. Click on the update, if it is found and uninstall it.
  6. Repeat steps 4 and 5 for KB3072630.KB3000988, and KB3008627.
  7. Reboot the computer and try installing Grapher again.
