Notecase Pro does not depend on aspell spell-checker, but if you want spell-checking feature activated, you need to install aspell.

Windows OS:

Windows installer already comes with libaspell.dll and "app/dict" directory with the English dictionary files, so Notecase Pro it will work "out of the box" here (after you enable spellchecker in the "General Settings" window - "Global" page). If you want to use some other language in the spellchecker,
you just need to install one or more dictionaries from ftp://ftp.lyx.org/pub/lyx/contrib/aspell6-windows/
After installation, dictionary data should be copied under "app/dict" directory inside the directory where you installed Notecase Pro

Linux OS:

on Linux, use your package manager to install aspell package
Additionally you need to install aspell dictionary for the language you want to check (for example aspell-en package for English language)

Maemo:

You can find aspell packages for maemo at: http://ftp.gnuab.org/debian/pool-armel/main/a/aspell/
You can skip installing the "-dev" packages, so install both "aspell" and "libaspell" package.

Zaurus:

I couldn't find aspell package for zaurus, so I've had to compile it myself.
If you have gcc compiler installed, this should be easy:
- download sources from http://aspell.net/ (aspell-0.60.5.tar.gz) and unpack
- run "./configure", "make" and "make install"
- you can now delete source directory

1. Start the setup program. You'll be asked to choose between standard and portable (meant for USB memory sticks) install. Just follow the installation steps to finish the install.

1. Fedora and other .rpm based distros

   Just double click the .rpm file to start the install process. If you have any unsatisfied dependency reported by the installer, instal it and try again.
   

2. Ubuntu and other .deb based distros

   Just double click the .deb file to start the install process. If you have any unsatisfied dependency reported by the installer, instal it and try again.
   

3. Sharp Zaurus (pdaxrpm) .ipk package

   "ipkg install notecase-pro_1.6.4_armv5tel.ipk"

4. Maemo platform (Nokia N800)

   Install as any other .deb package

5. Gentoo ebuild

   Gentoo distribution uses it's own package format. To install the package, you need to download "notecase-pro-x.y.z.ebuild" file from the download page (where "x.y.z" is replaced with latest version number). The Gentoo build is actualy built on Sabayon and requires newer GTK version 2.18.x. These steps will get your package fetched and installed to your system (example assumes Notecase Pro version 2.9.4 is being installed):
   
   sudo install -m 644 ./notecase-pro-2.9.4.ebuild /usr/local/portage/custom/x11-apps/notecase-pro/notecase-pro-2.9.4.ebuild
   sudo ebuild /usr/local/portage/custom/x11-apps/notecase-pro/notecase-pro-2.9.4.ebuild digest
   sudo echo "x11-apps/notecase-pro **" >> /etc/portage/package.keywords
   sudo echo "~x11-libs/gtk+-2.18.5 **" >> /etc/portage/package.keywords
   sudo echo "~dev-libs/glib-2.22.3 **" >> /etc/portage/package.keywords
   sudo emerge x11-apps/notecase-pro

1. You start the setup process by double clicking the .pkg file.
