IntelliJ IDEA是否适用于64位Windows系统？

Question

I have downloaded and installed IDEA 13.1. However, even having a 64-bit system, Windows has automatically installed the program in the folder Program Files (x86) , which is dedicated for 32-bit programs.

Is there another download for the 64-bit version or maybe a special setting to make it suitable for a 64-bit system?

Answer 1

In C:\\Program Files (x86)\\JetBrains\\${Intellij Idea version}\\bin , there is an executable called idea64.exe . This is for 64-bit systems. You can simply change your IntelliJ shortcut path to it.

You also need to add a new environment variable IDEA_JDK_64 pointing to your 64-bit JDK so IntelliJ can use a 64-bit JDK.

idea64.exe uses this JDK search sequence:

1. IDEA_JDK_64 environment variable
2. ..\\jre64 directory
3. system Registry
4. JDK_HOME environment variable
5. JAVA_HOME environment variable

如果安装了截至今日2016.3.2的最新版本，则在安装安装向导时会提示选择32位还是64位。

Answer 3

您需要安装Java SDK 64bit，以便显示安装IntelliJ 64bit的选项。
