During a fresh Applications Manager installation, a number of directories, files, and symlinks are created.
In some situations, such as when a core Applications Manager file or script is deleted by accident, rerunning the installation does not replace the missing file.
This is due to the existence of the $AW_HOME/data/extract_file.dat or %AW_HOME%\data\extract_file.dat (Windows) which is created during the initial installation process.
If this file is found during reinstall, the file extraction process is skipped.
To force extraction of all initial install files, delete the $AW_HOME/data/extract_file.dat or %AW_HOME%\data\extract_file.dat (Windows) before running the Applications Manager installation.
In rare occasions, deleting the extract_file.dat file and rerunning the installation has solved a behavior where all standard local Agent Jobs go into a Launch Error status due an unknown reason (no errors found).
