下载更新后,它会显示无法安装更新的错误.
卸载会话上下文时发生错误:(profile = epp.package.cpp,phase = org.eclipse.equinox.internal.p2.engine.phases.Uninstall,operand = [R] org.eclipse.rcp.configuration_root.win32 .win32.x86_64 1.0.0.v20130521-1847 - > null,action = org.eclipse.equinox.internal.p2.touchpoint.natives.actions.CleanupzipAction).文件D:\ eclipse\eclipse.exe的备份失败.无法删除:D:\ eclipse\eclipse.exe
我在win7和jdk1.7.0_21 64bit下运行它.
