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。
然而,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进行复制步骤。
我们所有产品都使用Wix属性“AllUsers = 1”构建,因此应为所有用户安装产品,而不仅仅是一个。
赞赏任何想法/建议。
由于 本
更新 我注意到,当运行问题msi包时,会显示以下行:
MSI(88:68)[12:15:50:235]:FindRelatedProducts:无法读取产品'{840C ... etc ..... 96}'的ASSIGNMENTTYPE信息。跳过...
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,您可以不受任何问题影响"PackageCode"
属性(INSTALLPROPERTY_PACKAGECODE
)的值,但是您无法获得"UpgradeCode"
属性的值ERROR_UNKNOWN_PRODUCT
3}}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中的错误,所以它并不总是如此。有时它会回到1605(ERROR_UNKNOWN_PROPERTY
)或1608(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products
)。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using System;

using System.Runtime.InteropServices;
using Microsoft.Win32;

// This buffer must be 39 characters long.
// The first 38 characters are for the GUID, and the last character is for
// the terminating null character.
[DllImport ("msi.dll", CharSet = CharSet.Unicode, SetLastError = true)]
internal static extern Int32 MsiGetProductInfo (string product, string property,
StringBuilder valueBuf, ref Int32 cchValueBuf);
}
class Program {
static int GetProperty(string productCode, string propertyName, StringBuilder sbBuffer) {
int len = sbBuffer.Capacity;
sbBuffer.Length = 0;
int status = NativeMethods.MsiGetProductInfo (productCode,
propertyName,
sbBuffer, ref len);
if (status == NativeMethods.ErrorMoreData) {
len++;
sbBuffer.EnsureCapacity (len);
status = NativeMethods.MsiGetProductInfo (productCode, propertyName, sbBuffer, ref len);
}
if ((status == NativeMethods.ErrorUnknownProduct ||
status == NativeMethods.ErrorUnknownProperty)
&& (String.Compare (propertyName, "ProductVersion", StringComparison.Ordinal) == 0 ||
String.Compare (propertyName, "ProductName", StringComparison.Ordinal) == 0)) {
// try to get vesrion manually
StringBuilder sbKeyName = new StringBuilder ();
sbKeyName.Append ("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Installer\\UserData\\S-1-5-18\\Products\\");
Guid guid = new Guid (productCode);
byte[] buidAsBytes = guid.ToByteArray ();
foreach (byte b in buidAsBytes) {
int by = ((b & 0xf) << 4) + ((b & 0xf0) >> 4); // swap hex digits in the byte
sbKeyName.AppendFormat ("{0:X2}", by);
}
sbKeyName.Append ("\\InstallProperties");
RegistryKey key = Registry.LocalMachine.OpenSubKey (sbKeyName.ToString ());
if (key != null) {
string valueName = "DisplayName";
if (String.Compare (propertyName, "ProductVersion", StringComparison.Ordinal) == 0)
valueName = "DisplayVersion";
string val = key.GetValue (valueName) as string;
if (!String.IsNullOrEmpty (val)) {
sbBuffer.Length = 0;
sbBuffer.Append (val);
status = NativeMethods.NoError;
}
}
}
return status;
}
static void Main () {
string upgradeCode = "{00140000-001A-0000-0000-0000000FF1CE}";
StringBuilder sbProductCode = new StringBuilder (39);
StringBuilder sbProductName = new StringBuilder ();
StringBuilder sbProductVersion = new StringBuilder (1024);
for (int iProductIndex = 0; ; iProductIndex++) {
int iRes = NativeMethods.MsiEnumRelatedProducts (upgradeCode, 0, iProductIndex, sbProductCode);
if (iRes != NativeMethods.NoError) {
// NativeMethods.ErrorNoMoreItems=259
break;
}
string productCode = sbProductCode.ToString();
int status = GetProperty (productCode, "ProductVersion", sbProductVersion);
if (status != NativeMethods.NoError) {
Console.WriteLine ("Can't get 'ProductVersion' for {0}", productCode);
}
status = GetProperty (productCode, "ProductName", sbProductName);
if (status != NativeMethods.NoError) {
Console.WriteLine ("Can't get 'ProductName' for {0}", productCode);
}
Console.WriteLine ("ProductCode: {0}{3}ProductName:'{1}'{3}ProductVersion:'{2}'{3}",
productCode, sbProductName, sbProductVersion, Environment.NewLine);
}
}
}
}
获取信息。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
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'
在我的电脑上产生正确的输出
ProductVersion
而不是{{1}}之前的错误。

您应该查看Windows Installer XML的部署工具基础。它有一个非常成熟的MSI Interop(Microsoft.Deployment.WindowsInstaller),它将使编写和测试此代码变得更加容易。
我看到你已经有了WiX(希望是v3 +),所以在C:\ Program Files \ Windows Installer XML v3 \ SDK文件夹中查找它。
