The best way to fix this, assuming you do in fact have 64-bit JRE or JDK on your system, is to specify in eclipse.ini exactly which JVM you want it to use.

This can happen when a system has more than one JVM installed, as is often the case on Windows 64-bit (for example, the JRE download page uses the bit-ness of the browser to determine what bit-ness download to offer you, and many people use(d) 32-bit browsers even though they run 64-bit Windows). Program Files is the folder where 64-bit Windows places 64-bit programs. Program Files (x86) is the folder where 64-bit Windows places 32-bit programs.

However, the version of Java that it's picking up is 32-bit, as indicated by where it is coming from, on this line: -vm C:\Program Files (x86)\Java\jre7\bin\javaw.exe Your version of Eclipse is 64-bit, based on the paths and filenames.
