This is a common issue on 64 bits platforms, because they support 32 bits and 64 bits applications, and in you case 32 or 64 bits Java.
Extract from Charles FAQ : If you are using the 32 bit version of Charles you must have a 32 bit JRE installed, and vice versa if you're using the 64 bit version of Charles you must have a 64 bit JRE installed.
Make sure you are installing the correct version of Charles (32 or 64 bits) with respect to your Java installation.

我自己装charles开始装了64位的，后来装成32位的就直接打开了
