<br>
I'm currently using Scilab 6.0.1 on Windows 7 with several
projects in progress that I don't want to put at risk. But I'm
anxious to give 6.0.2 a try. Is it safe to install it in other
folder? I mean, can both versions coexist or it is necessary
to uninstall 6.0.1 to prevent trouble?<br>

Yes, as written by Eric, you can install as many versions as you
want, official ones and development ones as well (to give them a
try and contribute to prevent bugs before official releases)
without any issues.<br>
This is a strong -- too little known -- asset of Scilab.<br>
<br>
For all official releases, by default there is one specific
SCIHOME directory per version. This means that each version has
its own configuration and preferences files (for the desktop,
scinotes, general, etc), history of commands file, etc, stored in
the related SCIHOME directory.<br>
You can simultaneously run different versions as well. But then
you have the history of commands for each version, not mixed. You
have to copy your scilab.ini or .scilab user init file in each
SCIHOME directory ; etc.<br>
<br>
It is possible to share the same SCIHOME directory, but it might
then cause some troubles.<br>
<ul>
<li>Launching scilab with the -scihome option is possible since
Scilab 6.0.1, to set SCIHOME by hand.<br>
<br>
</li>
<li>Different <a moz-do-not-send="true"
href="https://build.scilab.org/view/Scilab%20binaries/">development
versions</a> of a given branch (current, master,..) always
share (by default) the same SCIHOME directory. But this can be
worked around by using the -scihome option. Do not hesitate to
use development versions. They are often better (or even much
better) than official releases. It takes 3 to 5 mn to instal a
version (and set its launching shortcuts with -scihome if
required, and its preferences). So it is worth to do it. And
if for 20% of dev versions temporarily it does not work
better, then you have lost only 5 mn... Not so much ;-)<br>
</li>
</ul>
For "old versions", some incompatibilities may appear. For
instance, i can run all scilab versions from 5.3.3 to 6.0.2
without any issue. But when i run 5.0.0 <= versions <=
5.3.0, making graphics always crash the session (while it worked
well before). It could be due to some Java runtime library
incompatibilities, not necessarily due to recently Scilab
installations, but possibly to automatic Java updates. This is
unclear. When i run Scilab 4.1.2, graphics are OK and stable.<br>
