Hi, my friend asked me if he can access his kindle for pc reader from another computer.  I am not tech savvy and have no idea.  He is traveling between his home and his daughters home once a week while she is under going chemo for breast cancer.  If anyone has any easy to follow instructions for him please post them here he is a member but is rather posting shy.  Thanks in advance!

I haven't used the Kindle app for PC, but what he needs to know is whether the book actually downloads to his computer or whether it enables him to read online. 

If it downloads, then no, he'd have to have his own computer,  If he reads online, then all he needs is his ID & password.

ETA:  at least that has been my experience  -  perhaps Amazon has both ???

If Amazon is like B&N, the the Kindle app needs to be downloaded to his daughter's PC.  Then he can open the Kindle app on that PC and read the book there.  The book will not be downloaded to the PC, but he will just be reading it online in his Kindle library.

Reading on Kindle for PC

Click the Home button on Kindle for PC to visit the Home screen and read your downloaded books or access Archived Items.

To read a book using Kindle for PC:

1. Launch the Kindle for PC application.
2. Go to the Home screen if you aren't already there.
3. Double-click on the title you'd like to read.

To turn pages while reading: Click either side of the page edge, use the scroll wheel on your mouse, or use your keyboard's arrow keys to turn pages in your book.

It is a program that installs to the computer, it is not web-based.

i've used Kindle for PC for probably a year now, but only at home on one computer.

as far as i know, whether or not he can read on both computers depends on a couple of things - does his daughter already have it on her PC?  if so, and it's registered to her own amazon account, then no.  he'd have to deregister from her account, then register for his, and since that'd mean she couldn't read her books on it that wouldn't be good.

if his daughter doesn't have it, then he can install it on her computer, and register it to his amazon account, and then he's good.  reading on one will save the last read location, and pulling it up on the other he'll go straight to wher he left off.  [probably not an issue in this case, but i believe you can only register up to 6 'devices', which includes ereaders, phones, etc as well as Kindle for PC.  if he's already got several devices registered, he might run into a limit trying to add a new PC.  though i'm guessing if he had a mobile device to read on he'd just use that.]
