Eclipse ADT: Java was started but returned exit code=13

Question

Could someone one clarify why my Eclipse (http://developer.android.com/sdk/index.html) from ADT won't start? Every time I'm getting this error: --------------------------- Eclipse --------------------------- Java was started but returned exit code=13 C:\Program Files (x86)\Java\jre7\bin\javaw.exe -Dosgi.requiredJavaVersion=1.6 -Xms40m -Xmx768m -Declipse.buildId=v22.0.5-757759 -XX:MaxPermSize=256m -jar C:\Users\Alexey\Desktop\tmp\adt-bundle-windows-x86_64-20130729\adt-bundle-windows-x86_64-20130729\eclipse\\plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar -os win32 -ws win32 -arch x86_64 -showsplash -launcher C:\Users\Alexey\Desktop\tmp\adt-bundle-windows-x86_64-20130729\adt-bundle-windows-x86_64-20130729\eclipse\eclipse.exe -name Eclipse --launcher.library C:\Users\Alexey\Desktop\tmp\adt-bundle-windows-x86_64-20130729\adt-bundle-windows-x86_64-20130729\eclipse\\plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120913-144807\eclipse_1503.dll -startup C:\Users\Alexey\Desktop\tmp\adt-bundle-windows-x86_64-20130729\adt-bundle-windows-x86_64-20130729\eclipse\\plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar --launcher.overrideVmargs -exitdata bec_34 -product com.android.ide.eclipse.adt.package.product -vm C:\Program Files (x86)\Java\jre7\bin\javaw.exe -vmargs -Dosgi.requiredJavaVersion=1.6 -Xms40m -Xmx768m -Declipse.buildId=v22.0.5-757759 -XX:MaxPermSize=256m -jar C:\Users\Alexey\Desktop\tmp\adt-bundle-windows-x86_64-20130729\adt-bundle-windows-x86_64-20130729\eclipse\\plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar --------------------------- OK --------------------------- JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

Error occurs when IDE(eclipse) bit-version (i.e. 32 or 64 bit) and jre bit-version mismatch! I have downloaded the 64 bit version and it showed me the exact error. But 32-bit version worked really fine. JRE version (1.6 or 1.7) doesn't matter. I think you dont need to downgrade. Because in my case, I had Java Version 1.7.0_45, whereas SDK requires 1.6, but it still worked perfectly fine!
