来源：百度文库 编辑：高校问答 时间：2024/05/02 05:07:53
请高手帮忙解决问题:我先安装的是STEP7-MicroWINv3.2 SP3这个版本,卸载后又安装的是STEP7-MicroWINv4.0的试用版(有天数和次数限制),把这个4.0的卸载后,再安装别的版本就不能安装了!
错误信息如下:Unable to locate a valid executable for update,youmust select the directory where your previous version of Micro/Win or Micro/DOS is located).
在我选择一个文件夹后,错误信息:Still unable to locate a valid executable for updata,or current version already installed .Installation aborted.

只有用卸载软件来删了。你可以用windows优化大师的智能卸载来删掉它！
