在windows7上加载时，ODBC出现VB.NET表单问题。拒绝访问net framework文件夹

Question

我是vb.net新手..我们最近创建了一个表单，它在连接到iSeries之后加载列表。该表单在Win8上的运行情况与预期一致，也已与XPs进行了核对，并且工作正常。我正在编译该文件，并将.exe放到某个文件夹中，然后从该文件夹(即C:\My Programs\VB_Apps)运行应用程序。在编译过程中，我使用了any_cpu/x86/x64选项，也遇到了同样的问题。应用程序正在建立一个使用ODBC驱动程序的连接(也尝试了OleDB驱动程序，但也遇到了同样的问题)。当从iSeries调用应用程序时，窗口正在加载，但在连接时应用程序停止，并收到以下消息：

此错误在x64和x86计算机上都会发生。得到错误的机器的唯一共同特征是都使用win7。

有没有人之前遇到过类似的情况，或者知道我可能会做错什么？

Answer 1

尝试检查运行应用程序的用户是否有权访问路径。

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.config

将权限分配给用户。

Answer 2

用户有权限，我意识到的另一件事是，通过将或当前驱动程序从客户端访问odbc更改为iseries odbc，win7 x64起作用了。所有安装了win7 x32的电脑都不能工作。我认为我们需要用win8或更新的版本替换所有的win7，但这仍然是一个令我担心的问题，因为我没有一个给定的解决方案，以便信任我的应用程序可以在生产环境中工作。

到目前为止，提前感谢你
