As a last resort, you can recreate InstallShield project from scratch.

>When I build an InstallShield package using the new version of InstallShield (that came with VFP 9.0), I am getting this error message:
>
>ISEXP : error -6262: The directory table contains the entry ARPHELPLINK. This identifier is reserved ; defining it in the directory table will yield unpredictable results at runtime. Use the Direct Editor to rename this directory Identifier.
>
>
>InstallShield Help says: The ARPHELPLINK property is the Internet address for technical support. Product maintenance applets display this value.
>
>How can I correct this problem? I can't find any reference to ARPHELPLINK anywhere in my InstallShield project. I have specified no support URLs at all.
>
>Note: this IntallShield project was originally created using the version of InstallShield that came with VFP 8.0, so it might have some old obsolete settings.
