FC7下如何安装MyEclipse6.0

有哪位大侠知道如何安装MyEclipse6.0啊。。。小弟下载了MyEclipse_6_0M1_E3_3_Installer.bin，然后在终端
chmod +x MyEclipse_6_0M1_E3_3_Installer.bin
./MyEclipse_6_0M1_E3_3_Installer.bin
应该出现安装界面的。。。结果却：
Preparing to install...
Extracting the JRE from the installer archive...
Unpacking the JRE...
Extracting the installation resources from the installer archive...
The size of the extracted files to be installed are corrupted. Please
try to download the installer again and make sure that you download
using 'binary' mode.
Please do not attempt to install this currently downloaded copy.


有谁知道啊。。请解释下如何进行安装。。JDK和Eclipse都安装好了。。。谢谢
