Hi,I have just started to get my hands dirty in Windows development.I have a question ,rather it is more of a doubt.I have a 32 bit application that uses a few of the WMI classes like Win32_PublishComponentAction,etc. My 32 bit app is trying to dynamically load and use the WMI provider ,msiprov.dll ,to access these classes and a few of its exported functions .Since it is a 32-bit application it is trying to search for this DLL in the C:\Windows\SysWOW64\wbem . What I noticed is the 32 bit versions of these DLLs are unavailable in the Win 7 64-bit OS and Win Vista 64-bit OS.Though the 64bit version of this DLL is available in C:\Windows\System32\wbem folder.So ,I hope you see the problem. My question is ,are there any service packs Windows has delivered that provides these Dlls to its customers ?

Hi , I am afraid there is no such official Service Pack.
