请教各位高人,由于换电脑系统升至win7,32bit,安装了STEP 7 Professional 2010 SR1和SIMATIC_STEP7_V55_SP3升级包,把原来的项目拷过来后,打开原有项目,有的能打开有的不能打开了,不能打开的出现提示, 257:9 ----the project contains objects of the software package 'sinumerik 810d/840d',which cannnot be edited because the software package is not installed or exists in an earlier version.
自己更新了STEP 7模块目录,但问题依旧
hwupdates都是在线升级的,全部下载了,只不过安装时选择全部,看了下,只有部分被选中,不知道是不是这原因,选不中的提示:selection not possible,cannot install over a HW update supplied with the step7 version,,实在是没法了,求高人指教
