Software Installation Fatal Error

Software Deployment failure - Fatal Error


You are unable to deploy software and you get an error - Fatal Error during installation during the process.


You will encounter this error due to one or more of the following reasons:

  1. Prior existence of the Software.
  2. User Name mentioned in the Run As option under Define Configuration does not have the Privilege to install software.
  3. Generic machine-specific issues:
    • Not enough disk space for installation.
    • The temp directory is not clean.
    • A certain file on the machine is locked.
  4. Common Windows Installer problems:
    • The Windows Installer Service could not be accessed
    • Windows Installer Service couldn’t be started
    • Could not start the Windows Installer service on Local Computer


Remove files of earlier installations

Use Microsoft’s Windows Installer Cleanup utility to remove traces of previous installations. This utility does not remove files installed by the installation, which may need to be removed manually.

Ensure the User account has administrative privileges to install software

If you are running your installation on a Windows machine, you are more than likely the administrator of your computer. Follow these steps to confirm administrative rights on your home computer:

  1. Select Start > Control Panel > Administrative Tools > Computer Management.
  2. In the Computer Management dialog, click on System Tools > Local Users and Groups > Users.
  3. Right-click on your user name and select Properties.
  4. In the properties dialog, select the Member Of tab and make sure it states "Administrator".

Resolve Generic machine-specific issues

To check your hard disk space, follow the instructions given below:

  • Double-click my computer.
  • Select the drive to which the software is being installed.
  • Right-click the drive to which the software is being installed (usually, this is C: drive) and select properties.
  • On the general tab, note the amount of free space.

If you are certain you have enough space to install the software on your computer, something else is causing the error.

To clean the temp directory, follow the instructions given below:

To clean your Temp directory, you first need to determine its location on your hard drive. Then, you'll delete the contents of the directory using a MS-DOS command or through Windows Explorer. To determine the location of the Temp directory:

  1. Click Start > Run.
  2. Type deltree /y temp_directory_location\\*.*.

    For example: deltree /y C:\\Windows\\Temp\\*.*

  2. Navigate to the location of the Temp directory, for example, C:\\Windows\\Temp.
  3. Select Edit > Select All. Select File > Delete.
