Question

What Is Setup.exe?

Answer

Setup.exe is the "package" used to install an application onto your computer. The primary task of setup.exe is to transfer the application files from the source media, such as a CD, to your computer. Setup.exe installs installation engines, if necessary, and then decompresses the application files and installs them into the appropriate folders. Setup.exe starts the installation and cleans your computer of unnecessary files once the application is installed.
