Difficulty configuring SOAP

Hello everyone...

I'm very new to SOAP and I still don't know how to install and/or configure SOAP on my machine... I'm using it to reach Salesforce and update Salesforce registers....

but first of all i really need it installed on my PC, because the websites that I've been browsing through don't seem to get me the files to get SOAP installed on my PC... can anyone provide me some useful links, please? Thank you
