Yes, this will be possible only if the the official website is available any more or if the application is hosted on one of the websites listed through Google Search. However, to identify the correct version of the software, I recommend using the Search function from the Software Informer page: http://software.informer.com/search/
Input the "change folder icon" and then use the available results to identify your software. If you find it, click the big green download button to download it.
