Install Adobe Acrobat and Reader so I can retrieve pdf files.
I'm sorry but I can't figure out what you're trying to do. But if viewing PDF files is what you need to do, the free Adobe Reader should work just fine. You can download it from http://get.adobe.com/reader/
Adobe Acrobat (Standard or Pro) is used to create and enhance pdf files. It can of course read pdf files. Adobe Reader is used for the purpose Reader pdf files. If you only need to read pdf files, then Adobe Reader should do. The link Vikrant gave you should suffice to get you up and running: http://get.adobe.com/reader/
If you want to purchase Adobe Acrobat you can do so through the Adobe store (http://store.adobe.com)
