InstallShield 2020 ยป InstallScript Language Reference
Message
'else' : 'else' clause already encountered
Description
Two else statements were encountered in an if...endif block.
Troubleshooting Information
An if...endif block can include only one else branch. If you require multiple conditional branching, use an if...endif block that includes elseif statements or a switch...endswitch block instead.
