我使用 VB.NET 作为代码隐藏文件在 ASP.NET 中创建了一个 Web 应用程序。我正在使用 ProvideX.Script 类的 COM 对象连接到 Sage MAS90 ERP。在 Visual Studio 2010 中一切都工作正常。现在当我进入部署阶段时，问题就开始了......我在 Windows Server 2008 的 IIS7 中部署了我的应用程序。当我运行该应用程序时，出现以下异常... 这是我遇到异常的代码行...

Set oPVX = Server.CreateObject("ProvideX.Script")

我已授予 IUSR 和 IIS_USRS 帐户完全权限，但仍然得到这个错误。我还在 dcomcnfg.exe 中注册了 ProvideX OLE 服务器... 我不知道该怎么办...... plzzzzzzzzzzzzzzzzzzzz 帮助我，我必须在几天内提交该项目...

Everything was working fine in visual studio 2010. Now when I moved to the deployment phase, the problem gets started.... I deployed my application in Windows Server 2008 in IIS7. When I run the application I get the following exception...
This is the line of code where I get the exception...

Set oPVX = Server.CreateObject("ProvideX.Script")
