Installing vCenter 5.5 on Windows 2012R2

This post will detail all the steps required to install vCenter 5.5a on to a Windows 2012R2 guest machine, I should add that at the time of writing 2012R2 isn’t on the supported OS list and that there is an additional step that needs to be done to ensure that the installation succeeds first time.

You will need to get a copy of OCSetup.exe because for some insane reason Microsoft dropped the use of it in Windows 2012R2 (it’s present in 2012). As a side note you can also use a copy of the file from Windows 2008R2 if you don’t have 2012 available. Once you have a copy place it in the C:\Windows\System32 folder.

Next up you need to ensure that you have the 64bit version of the SQL Native Client for the version of SQL you’re running for the installation. In my case I am running SQL 2012 but here are some links to both SQL 2008 and SQL 2012 Native Clients.

Microsoft SQL Server 2012 native 64bit client

Microsoft SQL Server 2008 R2 SP2 native 64bit client

Once downloaded I placed it on my desktop for easy use.

I am installing vCenter Server 5.5.0a that was launched recently to fix the issue with Active Directory authentication failing when the SSO was installed on to a Windows 2012 Server, the fix prior to this release was to use a patched idm.dll file issued by VMware (more information can be found at
