我的电脑是win7 64位的系统,之前安装了过一次貌似没安装上,后来卸载了,而且注册表也清除干净了,现在安装了STEP 7 - MicroWIN V4.0 SP9的时候,提示以下内容
IN order to install a newer version of STEP7-Micro/WIN4.0,you must first uninstall STEP7-Micro/WIN4.0 from Add/remove programs
after completing the uninstallation , restart this setup this setup will now exit
求大神帮忙解决问题,
