On the Appeon installation menu, when clicking a component installation link that will launch InstallShield, the following error may occur: "1607: Unable to install InstallShield Scripting Runtime" or "1628: Failed to complete installation".

Cause A: This error often occurs if you click Install on the PowerServer setup program main page twice when the PowerServer component installation program is already running.
