The installation program fails with the message “Error 1608: Unable to create InstallDriver instance”
This is an InstallShield problem that can happen for the following reasons:
▪The Client for Microsoft Networks networking protocol is not installed on the computer on which you are trying to install UNICOM Intelligence Interviewer Server. If this is part of your company’s security policy, install the protocol temporarily so that you can install UNICOM Intelligence Interviewer Server and then uninstall it.
▪The dcomcnfg default security settings do not include the Installing User under the Launch and/or Default Access permissions. To set the necessary permissions, do the following:
1 Run dcomcnfg.
2 On the Default Security tab, click Edit Default in the Default Launch Permissions section.
3 Add the Installing User.
4 If necessary, make the same change in the Default Access Permissions section, and then click OK.
