Downloading updates as a file for later installation

Can updates be downloaded as a file, and then later used to update Quicken?
I use Quicken on my desktop and only have dialup service at home (56kps). My connecting speed is so slow, the updates frequently timeout. If I'm really lucky, it takes hours to download the update.
I would like to download updates as a file on my cellphone, transfer the file from my phone to the desktop via USB cable, and finally install the update.
Can this be done and how?
