JSI Tip 3690. Programs that use InstallShield may not start?

If you have insufficient Component Object Model (COM) permissions, you may receive either of the following errors:

Setup failed to launch installation engine: Access is denied.

                     OR

Error installing Ikernel.exe, access is denied.

To resolve this issue, grant yourself the necessary permissions:

1. Open a CMD prompt.

2. Type dcomcnfg.exe.

3. Select the Default Security tab.

4. In the Default Access Permissions section, Press the Edit Default button.

5. If you do not have Allow Access permissions, grant it.
