,我也是先装的STEP7,后装的STEP7-micro/win ,没有你说的现象。不过怪事年年有,我装的STARTER软件就打不开项目,显示:
the project is write-protected or is already being used by another process on a different computer
you can try to open the project write-protected .Changes may be lost on closing. do you want to open the project write-protected?
再点“YES”显示
Error occurred while opening the project
Access to the project has been denied.
