title: The program can’t start because MSVCR71.dll is missing from your computer. Try reinstalling the program to fix this program
body: <p>Long ago, I installed 32-bit Oracle SQL Developer 2.1 on a Windows XP (32-bit) machine. I have since moved to Windows 7 (64-bit) and copied the SQL Developer 2.1 from the old machine onto the new one.</p>
  
  <p>When I try to run <code>sqldeveloper.exe</code>, I get the following message:</p>
  
  <blockquote>

  </blockquote>
  
  <p>I know that this is because of 32-bit software which was installed in Windows XP is incompatible with 64-bit machine. Is there any alternative to open 32-bit software on a 64-bit machine, or do I need to install the 64-bit version of Oracle SQL Developer?</p>
