Programs that use the InstallShield program may not start, and you may receive one of the following error messages:
Setup failed to launch installation engine: Access is denied.
Error installing Ikernel.exe, access is denied.
This behavior can occur if there are insufficient Component Object Model (COM) permissions.
To resolve this behavior, set the necessary permissions that are needed to successfully complete the installation:
At a command prompt, type: dcomcnfg.exe. The Distributed COM Configuration Properties dialog box is displayed.
Click the Default Security tab.
In the Default Access Permissions section, click Edit.
Ensure that you have "Allow Access" beside your name.
If you do not have "Allow Access" next to your name, either modify an existing profile or create a new profile that has the necessary permissions.
Apply all the changes and attempt to run Setup.
If installation or initialization errors, or denial of access errors occur, you may not have sufficient COM permissions on the workstation or server to successfully complete the installation.
This behavior can also be caused by a logon script, domain policies, or file system permissions. If this behavior persists, contact InstallShield Technical Support at either of the following InstallShield Web sites:
