SQL Server 2012 installation silently fails I am trying to install SQL Server 2012 running setup.exe on 64-bit windows 8. After the "please wait" dialog, the installation center comes up. I chose "New SQL Server stand-alone installation", getting a new "please wait" dialog and then this window:



I press ok and comes to a dialog where the product key is input, I press next and accept the license terms, next again, leaves as it is, press next, the installation seems to start.

This should happen according to the text in the window: Scan for product updates, download setup files, extract setup files, install setup files.

After a while, the window dissapears and I get no message.

Nothing seems to be installed.

What really happened?
If this is RTM, I would recommend slipstreaming SP1 + the latest CU into setup before installing, and making sure you install from a local source rather than an ISO, network folder, external drive, etc.

To slipstream you can just download SP1 (likely SQLServer2012SP1-KB2674319-x64-ENU.exe) and/or a CU (CU3 is here; CU4 should be released any moment now) to a folder (say C:\SP1Updates\), extract the files (you should end up with .exe files like SQLServer2012-KBxxxxxxx-x64.exe and you can ignore or get rid of the source 4xxxxx_intl_x64_zip.exe files) and then run setup from a command line like so:

setup.exe /UpdateEnabled=1 /UpdateSource="C:\SP1Updates\"


Or you can download the slipstreamed ISO from here (they have slipstream in the name, just note they contain SP1 but no CU):

Microsoft® SQL Server® 2012 Service Pack 1 (SP1) (download link)

Some blog posts that go into greater detail about slipstreaming:


Installing SQL Server 2012 + Service Pack 1 + SP1 Cumulative update in one installation using SQL Server 2012 Product Update

You might also try the technique here, and you should be able to use slipstream here as well if you want (you'll just need to use a different PatchLevel, 11.00.3000.00 I believe):


SQL 2008/2008 R2/2012 setup disappears/fails when installing Setup Support files


In case that blog post disappears, I'm going to steal the content and paraphrase (since part of the instructions seem incorrect):


  
  Save the following in a .reg file and merge to populate the registry:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\110\Bootstrap]
"BootstrapDir"="C:\\Program Files\\Microsoft SQL Server\\110\\Setup Bootstrap\\"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\110\Bootstrap\Setup]
"PatchLevel"="11.00.2100.60"

  Next, copy the following files and folders from all of the media to: 

 C:\Program Files\Microsoft SQL Server\110\Setup Bootstrap\SQLServer2012

  Next, run setup from the new location, and it should proceed beyond the point of error this time.
  


(Note that I haven't tried this technique.)
