IBM Connections 5 on W2k12 strange agreement

If you need to install IBM Connections 5 on Microsoft Windows 2k12, i find some strange declaration :
in official documentation you can find that each component are supported on W2k12, but you must pay attention regarding DB2 and TDI .

About DB2 you must use DB2 10.1 fix 4 or later


 but is better if you install on W2K12 R2, in other case without R2 you must apply a silent installation.

About TDI, is very strange because in official documentation of Connections it's declare supported on W2k12 but if you try to run installer you received following error:




and if you check in TDI offical documentation you can verify that its not supported :-(

in order to solve this problem, you must run it in Compatibility Mode as Windows 7
you have some way to apply this Compatibility, following:

1. using GUI ineterface:

• Right Click on the TDI installer file and select Properties from the Context menu. For eg: Click on <ISO_Image>\windows_x86_64\ install_tdiv711_win_x86_64.exe and select Properties
• Click on the Compatibility tab.
• Under the Compatibility mode section, set the the check box to true for " Run this program in compatibility mode for "
• Under the drop down select Windows 7 .     
• Click on OK to apply the compatibility mode.
• Now run the installer and proceed normally. 

2. via Windows Registry

• reg.exe Add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\

  AppCompatFlags\Layers" /v "<your full path to exec file>"

  /d "WIN7RTM"

 3. set Environment Variable

•  set __COMPAT_LAYER=WIN7RTM
• and run your installer from the same command windows

using these precautions, you can install your Connections smoothly.
enjoy.
