What is the msdia80.dll and can I delete it?

    Question

  • I currently have msdia80.dll  on a drive.  It is the only file on that drive. I want that drive that msdia80.dll is on to be part of a SQL Cluster. There was originally a database on this drive, when I deleted the database the msdia80.dll remained on the drive. Can I delete the msdia80.dll ?

    I know I need to have the drive empty in order to install a SQL Server Node.  So What is the msdia80.dll and can I delete it?

    Thanks,

    CaptSky

    This file was apparently copied to the incorrect location due to a bug in the VC++ 2005 redistributable (which is used by some applications).  Detailed instructions on how to move the file to its proper place are outlined on this page: http://www.blindnero.com/forums/phpBB3/viewtopic.php?f=15&t=1288

  • Hi CaptSky,

    Thank you for your post.

    If your PC is running x64 operating system and you install Visual C++ 2005 Redistributable Package on this computer by using the Vcredist_x64.exe file or the Vcredist_ia64.exe file, the Msdia80.dll file will be installed in the root folder of the boot drive.

    If you have the same scenario as I described above, could you please try the workaround mentioned in the following similar issue to resolve this problem?

  • Hi,

    The Properties on the msdia80.dll file, Version > Name is Microsoft 2005 Visual Studio 2005.  Visual Studio 2005 is NOT installed on the SQLvServer1.  Since can delete it.

    Thanks for your assistance,

  • I currently have msdia80.dll  on my T  drive.  It is the only file on that drive. I also have the dll file on C:\Program Files (x86)\Common Files\Microsoft Shared\VC. I want to take the msdia80.dll  off of the T drive. I need to install a separate  SQL Cluster node on Drive T. There was originally a database on the T drive;  I deleted the database and msdia80.dll remained on the drive.

    We currently have the msdia80.dll on the C drive. We do not have Visual Studio on the SQL Server 2005 cluster.

    So, what do I need to do to get the msdia80.dll off of the T drive?  Can I delete it?

    Thank you,

    CaptSky
