Why do I get "The procedure entry point CreateVssBackupComponentsInternal could not be located in the dynamic link library VSSAPI.DLL."

Hello everybody let me give you the background first: I'm working on a project that is build with vs2005 on a winxp sp3 with the windows sdk 7.0 and most important the hotfix, that is targeted to work from win xp (sp 0) -> windows 7.

part of the project is querying the snapshots and play with the a bit. On my development environment everything is ok, on windows 7 everything is ok (Kinda ok but it's not the point).

On clean xp machines (sp3 & 2) I get: "The procedure entry point CreateVssBackupComponentsInternal could not be located in the dynamic link library VSSAPI开发者_如何学JAVA.DLL" when I start the application - Even before I get to the part in the code that is related to the VSSAPI...

1) how can it raise the message before I get to the invocation? 2) Does anyone has an idea why it doesn't work?

thanks

1) Because the DLL is loaded when your application starts, not when it's first needed. Look up delay-loading or the LoadLibrary system call if you want to load it later, or even conditionally.

2) I don't know, but someone asked the same question before: Why does my Volume Shadow Copy Service requester fail: cannot find CreateVssBackupComponentsInternal
