Eclipse Won't Start - JVM incompatibility

Question

I'm trying to open my Eclipse - and nothing happens, no window is opening. this is the warnings I got in D:\Eclipse\adt-bundle-windows-x86_64-20140702\eclipse\configuration\1424604493775.log

I understand that my JVM is incompatible with my version - but how do i fix it? Thank you!

Answer 1

You have a 32 bit JVM and 64 bit Eclipse. These should match, so download a 32 bit Eclipse or a 64 bit JVM.

Answer 2

As I see you are running on Win 64-bit.

First, install latest JDK 8 (64-bit) available thru java.com

Go to Control Panel->System->Advanced System Settings

Then Advanced Tab ->Environment Variables

System Variables on the bottom

Click New...

Add variable name JAVA_HOME

Add value c:\Program Files\Java\jdk1.8.0_31\ (should be this by default, check yours)

Click New...

Add variable name JRE_HOME

Add value c:\Program Files\Java\jre1.8.0_31\ (check your path)

Then select 'Path' variable in the list, click Edit...

Add to the end of string ;c:\Program Files\Java\jdk1.8.0_31\bin\;

That's all.

Please, reboot for now.

In command prompt make sure you can run commands:

java -version
javac -version

Answer 3

your problem is: Cannot load 64-bit SWT libraries on 32-bit JVM first google result is: Cannot load 64-bit SWT libraries on 32-bit JVM ( replacing SWT file )
