vCenter Server 5.5 setup stuck installing Directory Services

If you ever land up in a situation where your vCenter Server setup is stuck at the directory services stage and in the "VMINST.LOG" found under %temp% u see it trying to perform the following..

  1. VMware VirtualCenter-build-1235232: 02/20/14 09:48:55 Attempting to launch ["C:\Windows\system32\cmd.exe" /c start /w C:\Windows\system32\ocsetup.exe DirectoryServices-ADAM /passive /norestart]

Just go to anyone of your Windows 2008 R2 servers and copy the "ocsetup.exe" file from C:\Windows\System32 and place it on the vCenter Server under  the same location and try running the setup again and it should work!
