Drag and drop applications shouldn't install any additional files at first launch. Instead, please use an Apple installer to install all files that require administrator privileges to install.
My test machine (a virtual machine in Parallels) had never accessed the Internet and I had an issue with getting the privileged helper tool installed. Until I provided the VM internet access the application would only quit. This could have been avoided by using an installer rather than installing items at first run.
The Lightning app itself should be installed using an Apple installer package and that package should install not only the Lightning.app file into the Applications folder but also the com.filewave.strikeof.lightning.taskrunner file into /Library/PrivilegedHelperTools.
Installing additional files at first run of an application is bad form. Installers exist to place applications and supporting files onto the machine so that an application is ready to use when it's launched. This would have helped me avoid the problem I experienced in my particular testing scenario.
