I am using windows XP 32-bit and I have downloaded the SQL developer from the location http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html which included JDK1.6.0_35 but when I click on sqldeveloper.exe it says
"this application has failed to start because MSVCR71.dll was not found.Re-installing the application may fix the problem."
When I click on OK it says "Unable to launch the Java Virtual Machine located at path ../../jdk/jre/bin/client/jvm.dll "
Please help me out urgently.
Try the workaround given in a recent thread on this forum for the same issue: Workaround MSVCR71.dll is missing by placing a copy in <SQLDEV_HOME>\sqldeveloper\sqldeveloper\bin. If you downloaded the 32-bit version of SQL Developer with the JDK included, you can find that dll in <SQLDEV_HOME>\sqldeveloper\jdk\jre\bin.
So why does this happen? See the links in the following post for details: Re: sql developer fails to launch
SQL Developer Team
Doesn't fixing the MSVCR71 issue allow you start SQL Developer successfully and never see the jvm error message? In my past experience, I thought those message traveled in pairs! But if for some reason you are still having problems, you can bypass running the tool from an .exe and instead run directly from Java by using the sqldeveloper.bat file (see the post above my final post in the following thread): Sqldeveloper - Windows 7 64 Bit - unable to launch

In the referenced thread, note the disconnect between those two final posts: the other poster said using sqldeveloper.bat worked for him, not resetting the ORACLE_HOME. My reply, however, related to ignoring any other ORACLE_HOMEs on the machine. Not sure exactly why the sqldeveloper.bat file worked for the poster. Java actually does rely on MSVCR71.dll (Java 6) or MSVCR100.dll (Java 7).

Another alternate fix for Windows seems to be appending $JAVA_HOME/bin to the $PATH variable: The specified item was not found.
