问题描述
我正在使用 IIS 7.5 在 Windows 7 64 位上运行 C# ASP.NET 4.5 Web 应用程序.它使用的应用程序池名为ASP.NET v4.0"，其标识为 ApplicationPoolIdentity.该应用程序使用 MS Office Interop(Microsoft Excel 14.0 对象库).
I am running C# ASP.NET 4.5 web application on Windows 7 64-bit using IIS 7.5. The application pool it uses has the name 'ASP.NET v4.0' and its identity is ApplicationPoolIdentity. The application uses MS Office Interop (Microsoft Excel 14.0 Object Library).
在 wBook = wBooks.Add(Missing.Value); 行，它抛出以下错误:
At line wBook = wBooks.Add(Missing.Value);, it throws the following error:
Microsoft Excel 无法打开或保存更多文档，因为没有足够的可用内存或磁盘空间.
u2022 要获得更多可用内存，请关闭您的工作簿或程序不再需要.
u2022 To make more memory available, close workbooks or programs you no longer need.
u2022 要释放磁盘空间，请从您要保存到的磁盘.: 在Microsoft.Office.Interop.Excel.Workbooks.Add(对象模板)
u2022 To free disk space, delete files you no longer need from the disk you are saving to.: at Microsoft.Office.Interop.Excel.Workbooks.Add(Object Template)
1) 我在 DCOM 配置中给了帐户 IIS apppoolASP.NET v4.0 对 MS Excel 应用程序的完全控制权.
1) I gave the account IIS apppoolASP.NET v4.0 full control on MS Excel Application in DCOM Config.
2) 我赋予 IIS apppoolASP.NET v4.0 对C:WindowsSysWOW64configsystemprofile"的完全控制权，并在其中创建了一个桌面文件夹.
2) I gave IIS apppoolASP.NET v4.0 full control on 'C:WindowsSysWOW64configsystemprofile' and created a Desktop folder in it.
3) 虽然不推荐使用 Interop，但我需要继续使用它.
3) I need to continue using Interop though it's not recommended.
4) 该应用程序在 Windows Server 2003/Windows XP 32 位上运行良好.
4) The application works fine on Windows Server 2003/Windows XP 32-bit.
5) 机器上安装了 MS Office 2010(64 位，试用版).
5) MS Office 2010 (64-bit, trial version) is installed on the machine.
6) 我不想更改应用程序.从 ApplicationPoolIdentity 到 Network Service 等池标识.ApplicationPoolIdentity 是 IIS 7 中的新型标识，推荐使用.
6) I would prefer not to change the app. pool identity from ApplicationPoolIdentity to Network Service etc.. ApplicationPoolIdentity is the new type of Identity in IIS 7 and it's recommended.
如果我在 DCOM Config 中选择交互式用户"(我以管理员身份登录)，它工作正常，但会导致其他问题.我需要使用 ASP.NET v4.0 的启动用户".所以看起来这是一个权限问题.
It works fine if I select 'Interactive User' (I have logged in as an admin) in DCOM Config, but it causes other problems. I need to use 'Launching User' which is ASP.NET v4.0. So it looks like it's a permission issue.
请帮忙.谢谢.
推荐答案
用文件资源管理器右键单击文件，选择 Properties，然后选择 General 选项卡并单击解锁 按钮.此错误消息非常具有误导性.
Right click on the file with file explorer, choose Properties, then General tab and click on the Unblock button. This error message is very misleading.
