Windows Setup files(b55),
automatic desktop integration:
Despite claims to the contrary, some
Windows10 systems seem to be unable to reliably run wxWidgets
based Windows 7/8 programs. They may in some cases even make the
Explorer stall... See
the dedicated Windows10 versions below.
The installer for the windows version(XP,
7, 8, mostly also 10) comes in
two flavours:
A) aca_sig_setup_update
(-> this is the one you probably want.)
This one copies its files in place if they are newer
than the old ones. Passphrase hash, salts and secret files
containing keyinfo will be preserved. Thus, if a previous version
of academic signature existed, there will be no new hatching
procedure, login will require the familiar passphrase and all
previously known keys will still be accessible.
The modest uninstaller will consequently remove only program
binaries and will leave user specific secret or public
information in place for reuse with a subsequent install of
academic signature.
(In order to reenter into the hatching procedure you may
remove old login info by manually clearing the "x_sexrets"
dirtectory and then reinstall. Upon the third login failure
the location of this directory will be displayed by the
program.)

B)
aca_sig_setup_overinstall
(->this is the version for those guys who
forgot their passphrase.......;-))
This one pushes its files in place, deletes passphrase
info from previous versions and overwrites previous files. Watch
out, all previous passphrase, salts and keyinfo will be lost, but
old files will not pose an obstacle for fresh reinstallation.
The radical uninstaller consequently removes all traces of
academic signature and will enable you to start anew from scratch:

On multi user systems, where you are not administrator, do the following steps:
a) Ask the administrator to execute the installer. This copies the executables and some permanent Files to the program directory.
b) now call the
installer again with your non administrator privileges. This
sets the aca_sig_b data structure with x_secrets und key_tray
Folder. The rejection of the attempt to write the executables
again will produce some error messages you may ignore.
In case you called the installer yourself with administrator
privileges but want to use academic signature with non
administrator privileges, you should change the access rights
for the program data in aca_sig_b with x_secrets and key_tray to
read and write permission for your non-admin account.
I will try to implement this a little more comfortable in an
upcoming update.

Source Archives
Source archive as standard "autotools tarball".
Takes care of Linux 32/64-bit and wxWidgets 2.8/3.0
adaptations automatically. Users unzip, ./configure,
make, make install.
aca_sig_tarball,
ECDSA-Signature and GnuPG-signature thereof.
to compile, you need wxWidgets including the
dev-libraries
libwxgtk3.0-dev and libwxbase3.0-dev (or both
in version 2.8)
Alternate Academic Signature Source
alternate
archive ,
ECDSA-signature
and GnuPG-signature,
source code for Linux, version b55.
With manually created command line "makefile".
(You must copy the used images:
"unterschrift.png", "aca_sig_icon.png"
and "elliptic_m5_p4_360e_a.png" to the folder,
you set as
working directory manually.)

Hints and troubleshooting: A) The
precompiled Linux versions might not run on older versions of
ubuntu. So if a library seems to be missing, upgrade your system
to the current distribution and try again. If you plan to build
Academic Signature yourself, updating/upgrading your ubuntu/debian
prior to compilation would also be a good idea. And don't forget
to install wxWidgets in this case.
B) If you use the Alternate source and want to retain
an out-of-age version of ubuntu, you might have to compile
Academic Signature from the archive.
Watch out: The GUI tool wxWidgets 2.8 can be a bitch to work with
-> Some older versions are buggy, you may have an
intermediately aged version that steals the menu entries(only
shows them under Unity). Others may or may not require lX11 to be
linked explicitly(the makefile has it outcommented, you may have
to activate it again in some older wxWidgets 2.8 versions).
C) If you can, you should use wxWidgets 3.0.2 or higher. It
produces substantially larger binaries than 2.8, but has not shown
2.8's bitchy behavior yet ;-)
In case you have to use wxWidgets 2.8, you again have to manually
edit dolonu.h and activate the previously commented out line 27
containing the define: #define WX28 .
