There could be various causes to this issue. The first thing to try is to see what is the error or how the program behaves when you launch it and then proceed to the next step, but I would try to reinstall the application and then launch it again. In some cases, other program's uninstallers corrupt the files for the rest of the applications installed in your computer.
Secondly, the programs installed on your computer might cause compatibility issues with the one you want to run. Close all of them and then launch the software.
If you need to reinstall it, then you can download the software through the following link: http://sylcount-iv-lines-only-edition.software.informer.com/download/
