Error Message: Unable to install ISScriptxxxx.msi


Error Message: Unable to install ISScriptxxxx.msi


  • Product Name: CaliberRM
  • Product Version: 2005R2, 2005R2 SP1, 2006
  • Product Component: N/A
  • Platform/OS Version: N/A


When running the CaliberRM installer, this pop-up message displays just after hitting next on the initial information screen, and before the licensing agreement or configuration or selections are prompted for.? The full error reads as below:

"1: The InstallScript engine is missing from this machine. If available, please run ISScript.msi, or contact your support personnel for further assistance."


This normally occurs when there are multiple versions of InstallShield from previous installations of various products, though may occur from conflict with another application, or information from a previous install that was not cleaned out.? There are a?few possible?workarounds listed in?a recommended order for process of elimination, and simplicity.

  • A. As a first measure, eliminate conflicts due to another running application, or a recently installed application. This may include closing other applications, clean up of temp files/directories, a fresh restart of the computer, disabling some items that load on startup and if allowed within your environment temporarily disabling any antivirus or installation monitoring apps.
  • B. Next, try running the ISScript1150.msi (CaliberRM 2006) or ISScriptxxxx.msi directly and prior to running the full installer, corresponding to the version of CaliberRM being installed. This file will be located in the same directory containing the setup.exe file used to start the CaliberRM installation. If you have a problem running this by itself please refer to http://consumer.installshield.com/kb.asp?id=Q108340 for troubleshooting, or you may try just uninstalling as described in Step D.
  • C. Provided step B goes successfully, now try running the CaliberRM setup.exe again. Sometimes this will resolve the issue without the need for the next steps.
  • D. If in running the setup.exe again results in the same error message even though InstallShield seemed to install successfully in the previous step, there may be an issue with the various previous versions of InstallShield. To remove all of the existing versions InstallShield, right-click on the ISScriptxxxx.msi and choose uninstall. Afterwards, restart the computer and try re-running the CaliberRM setup.exe.
  • E.Finally there could be a problem with information stored by the Windows Installer service which utilizes the *.msi files. This can be caused by various issues, the most common being issues after an upgrade of the operating system.
    If you find that you are in this position, there is a tool available from the following link http://support.microsoft.com/kb/290301 , after the installation, run the file called Windows Install CleanUp Utility to help uninstall previous versions and clean up data stored regarding application installs, that may not have completed successfully the first time such as the first attempt to install CaliberRM that failed.

In the chance that this issue persist, please log a case with Borland Technical Support.
