系统是XP的时候，安装了MyEclipse（D:\Program Files (x86)\MyEclipse 5.5.1 GA\eclipse）。操作系统升级到Win7后，仅仅是将MyEclipse 5.5.1 GA目录拷贝了，并没有重新安装。
今天，开打eclipse.exe时报错，查看.log日志，

解决办法：修改links\com.genuitec.eclipse.MyEclipse.link文件中的path即可，
将path=D:\\Program Files\\MyEclipse 5.5.1 GA\\myeclipse
修改为
path=D:\\Program Files (x86)\\MyEclipse 5.5.1 GA\\myeclipse
即可，目的是找到eclipse所使用到的myeclise目录。
