If you mean how to make changes to the files, it should already be done.

If you mean how do you install it in admin, click on the Paypal->Start link. Use either method to fill in your  credentials. Then install the module you want and test it.

If neither is what you mean or if you are having problems doing either, post a more details question.

Express Checkout: Pass the in-store selected shipping rate to the Instant Update Callback request and keep the shipping rate selected when the available shipping rates are displayed.

Express Checkout: If a shipping rate has been selected in-store (eg, the customer did not use the "PayPal Check out" button on the shopping cart page but went through the in-store checkout procedure and selected Express Checkout as the payment method), keep the selected shipping rate when returning back to the store checkout confirmation page.

The online update packages for v5.011 and v5.014 contained a hardcoded "admin/" path to update the "admin/paypal.php" file - if a custom administration directory name is used, please delete the "admin/" directory, this should only contain one "paypal.php" file which the v5.011 and v5.014 online update packages created.

Express Checkout: Allow a custom stylesheet to be loaded to help with the styling and positioning of the checkout buttons shown on the shopping cart page.

Express Checkout: Add "id" to the checkout button html tags used on the shopping cart page.

An error occured during this update.

I have checked the rights on these 2 files and they both have the rights set to: 777

So what to do next?

This is a very common problem, If you check carfully you will find the permissions are not correct. I would imagin you are using  Filezilla FTP  to make changes? Filezila will not change permisions correctly it has not done this for some time. So you must access the server directly and change permisions on the server. Make sure both directory and files have required permisions.

777 is NOT correct on many servers. They will give a 500 error because this is a security exposure ("world writable files"). You start with the minimum permissions on any file (typically 644) and add "write" permissions (664, then 666) until you get it working. Very few servers now require PHP files to be marked "executable" (755, 775, 777). This applies to files that PHP needs to write to, and depends on how PHP is configured (especially, what user group it's running under).

777 was safe to do back in ancient times, when you could trust everyone sharing your Unix computer. You can't anymore, especially on a server shared with hundreds or even thousands of strangers. Giving them "world write" access to your files is asking for trouble. If someone blithely tells you to "chmod 777 your files", they're an idiot. Don't listen to them.
