After extracting sqldeveloper-2.1.1.64.45-no-jre.zip and executing sqldeveloper.exe, I received following error :

Unable to create an instance of the Java Virtual Machine

Located at path:c:\java\jdk\jre\bin\client\jvm.dll

Open ide.conf file from <SQLDEVELOPER>/ide/bin/ide.conf

In this file, change this line :
AddVMOption -Xmx512M
by
AddVMOption -Xmx256M

this is ok!!!
