Zero Install 2.12.0 (1.3 Mb) is an advanced system of installation application, can help you to run the program from the developer’s site without the actual installation of the system. All you need is small, for the installation of utilities, or use the portable version, then launch it, see the catalog of programs, and select the desired process of downloading and unpacking will be fully automated, you only need to launch the desired application.
Zero Install Program cache and every time you run a check for a new version of the cache can be deleted if your application is no longer interested. Please note that each program will be loaded in the folder, so you can simultaneously use multiple versions of the same design. As I understand, you can add your application to do that, just enter the URL path to program and configure some other options, generally a development like in front of you, I think it would be very helpful.
