what kind of programs have you got to install?
if the programs is ended with .tar.gz, then you could take a look at the following article
http://www.linuxquestions.org/questions/answers/15
if its a rpm, then you could type "rpm -i filename" in the terminal, it should install your software.
for more information, you could take a look at the documents that came with your distro, the one i have is called 'Maximum RPM' that came with Red Hat. or you could use the search option.
good luck!!
