Collection?was?modified;?错误的解决方法

自编了一个资料管理软件，使用vs2010，vb.net编写，运用到ADO?、Access2010，软件分为主界面和分界面，在使用过程中发现，关闭分界面的时候没有安装vs2010的电脑会弹出下面的错误，但是已安装vs2010的电脑则不会弹出错误，求各位大神知道这错误是怎么引起的。（注：全软件编程没有使用到foreach）

解决方案

安装下.net 4.0的升级补丁，以及microsoft ace 14.0驱动包看看。另外检查电脑是否感染了360等非法流氓软件。

解决方案二：

.net4.0都全部安装了，每台电脑都安装了一套office2010，但是只有安装了vs2010的电脑不会报错
