Setup has Detected the Need to Reboot this Computer


Setup has Detected the Need to Reboot this Computer

Why is This Happening?

Error encountered during installation:  "Setup has detected the need to reboot this computer. The system registry indicated that another installation program still has pending unresolved issues. These issues will be cleared when this computer is restarted. You will need to run this program again after the machine has been rebooted."
  • When you run a Setup program to install ANY application, Setup may try to update some files that your operating system is currently using.
    • For example, Setup may try to rename or to delete these files.
    • If Setup cannot update these files, Setup sets the PendingFileRenameOperations registry entry to a non-empty value.
    • You must manually restart your computer to update the files that your operating system was using during the installation process.
  • If you do not restart your computer, these files are not updated.
  • If you then try to install another application, Microsoft Windows Installer determines that the PendingFileRenameOperations registry entry is not empty.
  • Therefore, you receive the error message that "Setup has detected the need to reboot..."
