The link you provided is for the H710p adapter not the mini. Which is why it isn't working, not because of a 64 bit 32 bit issue, and what I had linked to is the adapter not the mini as I based it off of the link and not the title of your post. Try this one [URL] As to answer your questions about 64 bit, here is some additional information: WOW64 is Microsoft's implementation of 32 bit emulation, so that you can run 32 bit applications in a 64 bit environment. It is seamless, you don't have to do anything to run an application in WOW64. It has been used for any applications that have been installed that are not native 64 bit applications since 2003 x64. [URL] Some hardware firmware updates do have 64 bit versions, but for the most part separating the updates in 32 bit and 64 bit versions provides no benefit as it is updating the firmware and not a normal running application and the benefits that 64 bit applications provide are not needed for an updater, as it won't need more than 4GB of memory, or the better memory addressing that 64 bit applications provide. In production applications 64 bit is a big advantage but for an update that runs a single time and is not needed after that it is not improving the experience.  
Hi , I cannot find the correct version of this to run anywhere. The following page I think is the correct one: [URL] But I cannot get anything on that page to run under 2008R2.  Can someone pls help with the correct package to run?  Thx, John Bradshaw
