安装了WINDOWS7后安装STEP7，打开以前的项目，出现如下提示，是什么原因呢？是什么软件包需要安装？
one or more objects or a type connot be represented. server 'p7vrimdx.dll' for _P7VR_DRIVEO_MODULE_CT objects could not be loaded.
make sure the required software packages are installed.
问题补充：
还有一个提示：one or more objects or a type cannot be represented. Server ''p7vrislx.dll'' for _P7VR_CBP2_MD_ETER_CT objects could not be loaded.
Make sure the required software packages are installed.
这是否说明CBP2通讯板需要安装什么软件包？是什么包？
