Error -1024 when building a project

I am converting some very old (IWZ) projects to run under Windows 7.

I am getting the following error during a build.

Billboard table successfully built
ISEXP : error -1024: File C:\HIW\HIEHRAdmin4422\build0001\Dev\hiehradm.exe not found. Cannot stream the file into the Binary table
Binary table successfully built

As far as I can see there are on longer any references to this file in the project.

The application installs and runs OK, I was just wondering how the remove this error.

Thanks Jeff
