So I currently have a client who has a virus and a multitude of errors on her machine. She has an archaic client billing software suite from early 2000s. I need to reformat this machine but the cost of a re-download of this shitty horrible software is $500, so I need to figure out a way to reformat the drive and relocate her software suite without an actual CD. Does anybody know of a way to reinstall software without a CD? I am going to try some things but if anyone has ideas or tutorials on this I would greatly appreciate it.
