Just wanted to updated the thread with the solution that worked for us. This error appears under these conditions: 1) Installer is launched as root; and 2) Installer is launched from a path with only one or two directories: for example, /dir1 or /dir1/dir2; and 3) Installer was built by InstallAnywhere 2014 without SP1 (Service Pack 1) -or- Installer was built by InstallAnywhere 2014 SP1 but IAClasses.zip was erroneously included as a dependency in one or more “Execute Custom Code” actions. In our case, the error appeared even when we used InstallAnywhere 2014 SP1, because we were including IAClasses.zip as a dependency in our “Execute Custom Code” actions. After we removed this dependency, the error was resolved. Note that you don't need to specify the IAClasses.zip dependency even though you have to use it to build your custom code JAR.
