大家好啊,我在安装STEP7 V5.4的时候出现拉这样一个问题,希望大家能帮我解决一下,谢谢! 问题如下:在安装的时候出现拉一个对话框,对话框内容如下: Installation requirements The requirements for a successful installation have not been fulfilled,You must fulfil the following requirements to be able to install Automation License Manager on your computer successfully There are data on your computer which will be deleted the next time you restart the computer .This may lead to problems if you reinstall the software .Restart Windows and then start setup again. 我把电脑重启后,重新安装还是出现这样的错误,我装拉许多次都是这样,希望大家能帮我解决一下这个问题.谢谢!!
