Both of these tools use the ZeroG InstallAnywhere installer, which doesn't completely get along with Windows Server 2012. Luckily, there's an easy fix within Windows. You need to set the "Compatibility mode" to run with compatibility for "Windows 7". You need to perform this procedure on the setup.exe file for ITIC (under Install\ITIC wherever you've extracted the install images) and the install_tdiv71_win_x86_64.exe file in the TDI installer directory.
On each file, right click and select Properties.
Then on the Compatibility tab, click the "Change settings for all users" button at the bottom.
In the "Compatibility mode" section, select "Run this program in compatibility mode for:" checkbox.
Select "Windows 7" from the drop down list.
Click OK, then OK again.
And now you're ready to install
UPDATE: You do also need to ensure that the java executable is in your path. If not, it will fail when trying to create the Java Virtual Machine.
UPDATE 2: And it MUST be the Java 1.7 executable in your path. 1.8 will fail.
