	<li>Check the architecture of your computer (32 or 64 bit) and ensure you have the same Java version installed:<br />
	<br />
	OS X computers running OS X 10.6 or later have 64 bit computers.<br />
	<br />
	To find out if your Windows computer is running 32 or 64 bit, <a href="http://windows.microsoft.com/en-us/windows/32-bit-and-64-bit-windows#1TC=windows-7">click here</a>.<br />
	<br />
	If your Windows computer is 32 bit, go to &quot;Options &gt; Maximum memory (MB)&quot; in the launcher and type in &quot;2048&quot;.<br />
	&nbsp;</li>
	<li>Check your Java version:<br />
	<br />

	<br />
	<a href="http://www.wikihow.com/Get-to-the-Command-Line-on-a-Mac">On OS X, follow these instructions ot open Terminal.</a><br />
	<br />
	Type in &quot;java -version&quot; in Command Prompt or Terminal.<br />

	<br />
	​<code style="margin: 1.5em 0px; padding: 0px; border: 0px; font-size: 12px; font-family: 'andale mono', 'lucida console', monospace; vertical-align: baseline; font-stretch: normal; line-height: 18px;">java version &quot;1.7.0_55&quot;</code><br style="font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 12px; line-height: 18px;" />
