  • 1.1 Installation Prerequisite Handling During SQL Server 2012 RC 0 Setup

    •Installing SQL Server 2012 RC 0 is supported only on Windows 7 SP1 or Windows Server 2008 R2 SP1. However, Setup does not block installing SQL Server 2012 RC 0 on Windows 7 or Windows Server 2008 R2.

    Actually it does block on windows 2008 R2 and does not allow to install. I was trying to upgrade the client components from CTP3 on my dev box and it has windows 2008 R2 but no SP1 update.

  • Fantastic!!

  • In the first paragraph: "To read the original release notes document, click here" But unfortunately the link is missing...

  • Thanks Zoltan! I updated that link. It's not a big difference though, because most of the edits were all made by Microsoft technical writers.

  • 10.2 Install Upgrade Advisor (English-US) fails.   The dialog that pops up contains an incorrect link for how to resolve the issue.  The correct linke is ????

  • Had an issue when upgrading to SQL Server 2012, which wasn't mentioned in either the release notes or database upgrade advisor.  Got the following error when attaching an existing database with filegroups from an earlier version:

    Msg 3415, Level 16, State 2, Line 1

    Database 'abc' cannot be upgraded because it is read-only, has read-only files or the user does not have permissions to modify some of the files. Make the database or files writeable, and rerun recovery.

    Initially thought it was caused by NTFS permissions or the file read-only attribute was set.  However, it was due to filegroups in the database flagged internally as READONLY.

    The only way to get around this is to reattach the database to the earlier version of SQL and reset the READONLY flag on the filegroups.  This caused us a real headache as we had to copy the large database files over the network to the original server and then re-copy it back to the new server to attach.

    Although, this has been raised before (see below), there is scant documentation regarding this particular issue.  IMO, this should be highlighted by the upgrade advisor, or at a minimum mentioned in the release notes.

  • Microsoft Visual Studio 2010 does not support Microsoft SQL Server 2012 (when trying to add a connection in the IDE)

  • Wait.  Are you saying you cannot install SQL Server 2012 on Windows 8????
