The Flash Player MSI install installation fails with the following error message on computer where the logged-in user does not have administrative privileges.

1: ISMsiServerStartup Failure, Failed to Initialize script support, Error = 0x80070006

Important: This TechNote is only pertinent to customers deploying Flash Player installations using a distribution mechanism such as Microsoft SMS. Flash Player MSI installer name is "install_flash_player_active_x.msi."


Remove the runas parameter from this registry to force that object to work in the security level of the program that is calling it. If it is being called as SYSTEM, it works under those credentials. The path to the ISScript10 application ID is found in the registry here: HKEY_CLASSES_ROOT\AppId\{24D495A5-A174-4945-819D-CF294600C500}.

However, Flash 8 installer reinstalls ISScript10 each time it is run, and puts that runas "interactive user" in place each time it installs. Using a transform to remove the EngineStartup.4F635B62_07BF_4779_B74E_D80C29D508E3 row from the InstallExecuteSequence tables prevents Flash from putting that runas line back in place.

Additional Information

The Flash Player MSI installs correctly when distributed on computers where all logged in users have administrative privileges. If ISScript is not installed on the target computer, installing it adds the runas line. To avoid this issue, drop the row in the ISScript MSI install that adds the runas line. For ISScript10, remove the Registry601 and Registry6010 from the Registry table.


This error is most likely a DCOM privileges issue. DCOM (Distributed Component Object Model) allows communication and manipulation of objects over a network connection.

There are a set of keys in the registry under HKEY_CLASSES_ROOT\AppId. These keys are application IDs for DCOM objects. The ISScript which Flash 8 uses to install relies on DCOM. The default runas parameter for ISScript 10 is "Interactive User." SYSTEM is not an "Interactive User."
