    What is "Msdia80.dll" doing in the root of my storage disks?

    I am running Vista x64 Ultimate & other apps on a 150GB WD Raptor. Storage is taken care of by 2 x 1TB WD SATA2 drives in a RAID 0 setup.

    I noticed that the file "msdia80.dll" is installed in the root of the storage drives.

    I googled around a little and found this MS Hotfix: FIX: The Msdia80.dll file is installed in the root folder of the boot drive when you install the Visual C++ 2005 Redistributable Package by using the Vcredist_x64.exe file or the Vcredist_ia64.exe file that addresses a similiar, but not exactly the same problem. In that fix they want you to move the wayward "msdia80.dll" into the path \Program Files\Common Files\Microsoft Shared\VC\ . My problem is that I have all of that path with the exception of the \VC subdirectory.

    Can I manually create the subdirectory, move the file there and procede with the MS fix?

    I would leave the file where it is but I am thinking about uncoupling the two 1TB drives from their RAID 0 and instead using them as discrete drives. I suspect there will be a little collateral damage to any files on these drives when I uncouple but the machine is brand new and there isn't much stored there yet.

    Thanks for any insights or suggestions that anyone wants to throw my way.

    Sorry that this post is so long after yours, but I have just had the problem myself.

    I searched my registry for the dll and found it listed under only one path (other than the dll registration path which was the drive where I found the file). On my system that is: c:\Program Files (x86)\Microsoft Visual Studio 8\Common7\Packages\Debugger. There was no copy off the dll under that path so I copied it there and then ran the workaround from MS. Ie: regsvr32 "c:\Program Files (x86)\Microsoft Visual Studio 8\Common7\Packages\Debugger\ms\msdia80.dll".

    Nothing has broken yet!

    I think the instalation that caused the problem in the first place was that of the ATI Catalyst driver, which installs the C++ redistributable.

    I hope this helps. Cheers.
