Using Microsoft’s SQL Server Management Studio’s Import and Export Wizard, I would get “Unexpected Unrecoverable Error” message when I would click “Messages…” or view a report when an import failed. This was very annoying and I wasn’t getting any work done this way.
Thanks to the SQL Server Forums I was able to resolve this issue by installing the Extended .NET Framework 4. If you have the Client Profile version installed, you will still apparently get this error. Be sure to do a Windows Update after the install as there is a security patch for it.
BTW, this import Wizard is a big fail for Microsoft. SQL Server 2000′s version did much more – now my life is just plain more difficult thanks to their “upgrade” – just say’n.
I am running SQL Server Management Studio 2008 R2 64-Bit on Windows 7 64-Bit.
