On HP-UX, two types of error messages that occur during installation can be ignored and have no impact on the InstallShield installation:
When in GUI mode, the installation procedure displays “gif file not found” messages in the console before the GUI interface is displayed.
When you create a response file for silent installations the installation procedure displays “Illegal character ‘8’ in encoding name” messages. These error messages have no effect on the functionality of the response file created and on a successful silent installation. Additionally, some of the comments inserted into the response file are not formatted correctly and can also can be ignored.
