Downloading and installing the SCCM 2012 prerequisites

There are a number of prerequisites to install on your server before running the SCCM 2012 installer. Even once the SCCM installer is running, it wants to download some more prerequisites. If you are installing onto a non-network connected machine for testing purposes, you'll need to grab these files by running the installer on some other network connected machine beforehand. I ran this on my Windows 7 x64 workstation, but any modern 64-bit Microsoft OS should do.

From a CMD prompt-

1. Create a folder for the downloaded files (eg mkdir c:\sccm2012prereq)
2. Navigate to smssetup\bin\x64 in the SCCM 2012 source directory
3. Run setupDL.exe c:\sccm2012prereq

You will also need .net Framework version 4.0. This is downloaded as part of the prerequisite step so you can install it on your server from the sccm2012prereq folder. There are two installs, you need to use the dotNetFx40_Full_x86_x64.exe, not the client version as noted in the release notes. Surprisingly the SCCM 2012 installer doesn't automatically install this.

Before you can install SCCM 2012, you'll also need to install SQL Server (I'll cover this in a later post), and some roles and features for Server 2008. The roles and features can be easily installed with the following commands-

servermanagercmd -install web-server
servermanagercmd -install web-mgmt-compat
servermanagercmd -install rdc
servermanagercmd -install bits
