Eclipse / Java是否可以在Windows 7 64位上运行？

Question

I noticed a lot of problems when trying to run Eclipse and Java on 64 bits MS Windows. Is it supported? Is this something I shouldn't do or try to do?

I extracted Eclipse helios 64 bits zip, then I installed Java and I was able to run Eclipse for day or two.

Now I have been working hard for a few hours to reproduce a working Eclipse and I am arriving at the conclusion that probably it is not such a good idea. It is 64bits OS, 64 bits Helios, 64 bits Java. Could it possibly work?

Java runs on billions of device supposedly but I doubt if it will ever run 'again' on my laptop. If it does work I suppose it is just luck.

Answer 1

Uninstall everything and try downloading fresh again. I am using eclipse in my 64 bit windows machine for long time now and it works fine.

Try using versions which I am using currently. These work perfect for me - jdk1.7.0_21 and jre7 and eclipse version 3.7.2

Answer 2

Now, I am using 64-bit Windown 7 with JDK 1.6.xxx. There is no any problem.

Make sure JAVA_HOME to do enviroment variable. Otherwise, you need to configure vm configuration in eclipse.ini . You also note of that memory setting for eclipse. It is base on your physical memory.

eclipse.ini
