calibre Portable (32/64 bit)

"The bottom line is that you should use Calibre. Why? Because although it is chock-full of features and customizations and it’s actually incredibly easy to use, allowing you to spend less time learning how to use it and more time managing and reading your books." —Aaron Couch, MakeUseOf.com (October 16, 2012)

"Excellent program. While some of the options are a bit obscure to find or work with, it will allow you to do nearly anything. ...it's tech friendly but not particularly user-friendly. I still rate it 5 stars because of its wide range of features and options, the ability to edit eBooks directly, and its streaming library capabilities. Needs some user-friendly work but still an OUTSTANDING program." —furrepanther (a user), SourceForge.net

"Calibre requires import (copying) of the users books. If the number is small, Calibre is OK. If the number is large, ... then Calibre creates problems..." —nobicycle (a user), SourceForge.net

msiexec /a "___.msi" TARGETDIR="[FULLDIRPATH]\___" /lv*x! "___.txt" /qn
Copy the full command line in NPP and replace the "___" with the msi installer name, and "[FULLDIRPATH]" with full path to current folder, in this example C:\0TEST:
msiexec /a "calibre-3.14.0.msi" TARGETDIR="C:\0TEST\calibre-3.14.0" /lv*x! "calibre-3.14.0.txt" /qn
Then paste it in a command window: press SHIFT → right-click on empty space in File Explorer → select "Open command window here" → paste the command line into the command windows → press ENTER, then you can close the window,

Watch the progress by switching File Explorer view to "Details", so you can see the log file size increasing,
When it stops increasing, open the log with NPP. The extraction is completed if you see this at the end of the log:
Do the same thing with the other msi installer.
We'll move calibre and calibre2 folders from extracted msi installers to calibrePortable _3264\App,
