Computer software installation problems

Users questions: My friend helped me in a game jumped the pieces of software, I only know that the software in the Add or Remove Programs in there, then I have to look at how to copy the software and then install it to another computer? Another computer I have the software.
Experts answer: Unfortunately, the software can not be re-installed Extract files and folders, and then again to install another computer. In fact the software installation process is quite complicated, especially large-scale software, the installation process will be c: * windows, c: * windows * system32, c: * programfiles Article Slice and so generate a large number of files under the folder, to 11 to find out which program they belong to, is almost impossible, in addition, the installer will write in the registry thousands of records, we all know, the registry is a very complex stuff, to identify each key, and also mission impossible. more Do not say that for the normal operation of the software, the installer also registered in the system a series of ActiveX controls. In short, has been re-installed software can not install to other computers (except for green software because usually they only need to can run an executable file).
