<p>
	gvSIG can run in a 64 bits computer provided that the Java Virtual Machine which uses gvSIG is a 32 bits one, since this platform is where binaries are compiled for currently.</p>
<p>
	<strong>Windows</strong></p>
<p>
	By default gvSIG for Windows uses the system default JVM, so it will be necessary to assure it is a 32 bits one. If, for any reason, default JVM must be 64 bits, it is possible to force gvSIG to use another JVM different than the default one.</p>
<ul style="margin-left: 40px;">
	<li>
		<strong>gvSIG 1.11:</strong> It will be necessary to edit gvSIG.ini file (at the "bin" folder of the gvSIG installation folder) and change the system JVM directory for the 32 bits one.</li>
	<li>
		<strong>gvSIG 1.12:</strong> It will be necessary to install an add-on that will install a 32 bits JVM and force gvSIG to use it. Consult instructions at the <a href="http://blog.gvsig.org/2013/02/28/solution-for-gvsig-1-12-problems-in-windows-64bits-operative-systems/" target="_blank">gvSIG blog</a>.</li>
	<li>
		<strong>gvSIG 2.0:</strong> This version has an add-on included that force gvSIG to use a 32 bits JVM.</li>
</ul>
<p>
	<strong>Linux </strong></p>
<p>
	In Linux case, by default, gvSIG installs a valid and exclusive for gvSIG JVM, so accepting installation default options, there will be no problem.</p>
