Why do I get an error message Error 1628/1607: Failed to complete script based install or Unable to install InstallShield scripting runtime, when I try to run the installation software?


  • These error messages are often caused when the user does not have the administrator right of the computer or installation done on a network computer.
    • To run most installations on Windows XP machines, you are often required to be the administrator of the computer or have some kind of administrative privileges. The reason why installations require administrative privileges is because many times installations access the Windows registry and Windows System folders. If you are trying to install software on a computer in a corporate environment, you need to contact your system administrator to give you administrative privileges on your computer.
  • You may have insufficient disk space in your computer to install the program. Please erase unwanted files to make room on your computer to run the installation.
