我的 Delphi XE8 应用MyApp.exe因EOleException而失败
ErrorCode = -2147024770 {$8007007E},
Message = 'The specified module could not be found'
Source = 'Microsoft OLE DB Service Components'
，遗憾的是没有提供有罪模块的名称。
使用ConnectionString首次尝试通过 ADO 和 IBProvider 访问 Interbase XE7 时出现异常
Provider=LCPI.IBProvider.3.Lite;
Password=masterkey;
Persist Security Info=True;
User ID=SYSDBA;
Data Source=AFGIR;
Location=localhost/IBXE7D:E:\DvpData\Test.ADO\IB_XE7\AFGIRG7.IBXE7;
ctype=UTF8;
ctype_user=ACP;
dialect=3;
auto_commit=True;
dbclient_library="C:\Program Files (x86)\Embarcadero\IBXE7D\bin\gds32.dll";
没有dbclient_library属性的相同ConnectionString（即使用默认客户端库）会导致相同的错误。
在IB访问尝试之前和之后存在于内存中的模块是相同的（根据 Process Explorer ），即：

MyApp.exe在3周前工作正常。据我所知，没有什么东西在源头上被改变了。我怀疑系统的“附带”不连贯性。同时，系统文件检查器找不到连贯违规， DependencyWalker 不会给我任何相关的（对我来说）指示。
Q1。您是否知道如何查明错误原因？
Q2。是否存在与Microsoft OLE DB服务组件相关的所有 DLL列表，或者更好的是，一个程序检查它们在系统上的连贯存在？
亲切的问候， JK
