使用MSIEnumRelatedProducts和MSIGetProductInfo的MSI Interop

Question

在使用MSI Interop API时,我遇到了一些导致应用程序崩溃的异常行为.这很简单,可以"处理"问题,但我想更多地了解"为什么"这种情况正在发生.

我对MSIEnumRelatedProducts的第一次调用返回值0并正确地将我的字符串缓冲区设置为productcode.我的理解是,只有当给定的升级代码(作为parm传递给方法)当前安装了"相关的系列产品"时才会发生这种情况,否则它将返回259 ERROR_NO_MORE_ITEMS.

但是,当我随后使用相同的产品代码调用MSIGetProductInfo时,我得到返回值1605,"此操作仅对当前安装的产品有效.".

在这种情况下,有没有人有任何想法？它在一台机器上是100%可重复的,但我还没有设法在另一台机器上获得再现步骤.

我们所有的产品都使用Wix属性"AllUsers = 1"构建,因此应该为所有用户安装产品,而不仅仅是一个.

任何想法/建议表示赞赏.

谢谢Ben

更新: 我注意到在运行问题msi包时记录了以下行:

MSI(s)(88:68)[12:15:50:235]:FindRelatedProducts:无法读取产品'{840C ... etc ..... 96}'的ASSIGNMENTTYPE信息.跳绳...

有谁知道这可能意味着什么？

更新:代码示例.

do
{
   result = _MSIApi.EnumRelatedProducts(upgradeCode.ToString("B"), 0, 
                                        productIndex, productCode);
   if (result == MSIApi.ERROR_BAD_CONFIGURATION ||
       result == MSIApi.ERROR_INVALID_PARAMETER ||
       result == MSIApi.ERROR_NOT_ENOUGH_MEMORY)
   {
      throw new MSIInteropException("Failed to check for related products", 
                                     new Win32Exception((Int32)result));
   }

   if(!String.IsNullOrEmpty(productCode.ToString()))
   {
      Int32 size = 255;
      StringBuilder buffer = new StringBuilder(size);
      Int32 result = (Int32)_MSIApi.GetProductInfo(productCode, 
                             MSIApi.INSTALLPROPERTY_VERSIONSTRING, 
                             buffer, 
                             ref size);

      if (result != MSIApi.ERROR_SUCCESS)
      {               
         throw new MSIInteropException("Failed to get installed version", 
                                        new Win32Exception(result));
      }

      version = new Version(buffer.ToString());
   }

   productCode = new StringBuilder(39);
   productIndex++;
}
while (result == MSIApi.ERROR_SUCCESS);

我想您尝试使用MsiGetProductInfo获取其他属性,如文档中所述.例如,你可以在没有任何问题的情况下获取"PackageCode"property(INSTALLPROPERTY_PACKAGECODE)的值,但是你无法获得"UpgradeCode"关于MsiGetProductInfo的属性值并收到错误1605(ERROR_UNKNOWN_PRODUCT).

更新:好的,现在我明白了你的问题.你如何在互联网上找到MsiGetProductInfo中的一个错误,所以它并不总是如此.有时它会回到1605(ERROR_UNKNOWN_PRODUCT)或1608(ERROR_UNKNOWN_PROPERTY).在这种情况下,唯一的解决方法是手动获取版本属性.我可以使用Microsoft Office Outlook 2010 MUI(UpgradeCode ="{00140000-001A-0000-0000-0000000FF1CE}")重现您在我的计算机上描述的问题,并编写了一个解决方法,我从注册表中获取产品版本.在示例中,我仅从中获取信息HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products.如果您对所有用户安装的产品感兴趣,则必须修改该程序.这是代码

            return status;

                    //  NativeMethods.ErrorNoMoreItems=259
                    break;

            }
        }
    }
}

在我的电脑上产生正确的输出

ProductCode: {90140000-001A-0407-0000-0000000FF1CE}
ProductName:'Microsoft Office Outlook MUI (German) 2010'
ProductVersion:'14.0.4763.1000'

ProductCode: {90140000-001A-0419-0000-0000000FF1CE}
ProductName:'Microsoft Office Outlook MUI (Russian) 2010'
ProductVersion:'14.0.4763.1000'

而不是ProductVersion之前的错误.

您应该查看Windows Installer XML的Deployment Tools Foundation。它具有非常成熟的MSI Interop（Microsoft.Deployment.WindowsInstaller），这将使编写和测试此代码更加容易。

我看到您已经有了WiX（希望是v3 +），所以请在C：\ Program Files \ Windows Installer XML v3 \ SDK文件夹中查找它。
