title: How to start Oracle SQL Developer 4 using 32 bit JDK on Win 64?
body: <p>I need to connect to a database and use a wallet file. 
  If i try with my SQL Developer i end up with "ocijdbc.dll: Cant load IA 32bit .dll on a AMD 64-bit platform." </p>
  
  <p>I have both installed JDK 32 bit (in C:Prog32bit) and JDK 64 bit (C:Prog) for development. </p>
  
  <p>I tried to set JavaHome in sqldeveloper/bin/sqldeveloper.conf manually
       SetJavaHome C:\Program Files (x86)\Java\jdk1.7.0_51</p>
  
  <p>My next step was to edit %USER_HOME%/sqldeveloper/sqldeveloper.conf and I set SetJavaHome there too, but none didn't work. </p>
  
  <p>Next step was, i edited sqldeveloper/bin/sqldeveloper.bat and set: </p>
  
  <pre><code>JAVA_HOME="C:\Program Files (x86)\Java\jdk1.7.0_51"
  path="C:\Program Files (x86)\Java\jdk1.7.0_51\bin%"
  
  java.exe -Xmx640M -Xms128M -Xveri.... 
  </code></pre>
  
  <p>My last try was to use the command line (as I would do on linux) and run: </p>
  
  <pre><code>D:\sqldeveloper&gt;PATH="C:\Program Files (x86)\Java\jdk1.7.0_51\bin"
  D:\sqldeveloper&gt;java -version
  java version "1.7.0_51"
  Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
  Java HotSpot(TM) Client VM (build 24.51-b03, mixed mode, sharing)
  D:\sqldeveloper&gt;sqldeveloper.exe
  </code></pre>
  
  <p>But i still receive the message sqldeveloper is running 64 bit Java. </p>
  
  <p><strong>I found a workarround.</strong> An older version of SQL Developer (bundeld with jdk) is available at <a href="http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/sqldev-downloads-v322-2080107.html" rel="noreferrer">http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/sqldev-downloads-v322-2080107.html</a></p>
