is there a way that you can add certain programs from a computer and send them to other people?

Question

Sharing

Answer 1

Depends on the programs. If they depend on registry entries, sending the files won't be sufficient. Read the EULA, it is probably prohibited.

Answer 2

Not really. In most software the installer doesn't just copy files to a specific directory, it also copies them to system directories and makes changes to the computer's registry. You'll need the original installer. There's also the issue of legality - copying commercial software is illegal in most cases.
