The program fails installation, as you may have guessed already. So this is a small guide to get through the installation on a 64-bit machine running Windows 8 developers edition.
Error 1:
Crashes upon selecting install after launching the setup program.
Solution - select "Install Tools & Utilities" then agree to the licence agreement and press next. Press back then back again to get back to the screen with the install button once again. Select install.
Error 2:
Fails to install Microsoft Visual C++ 2008 SP1 Redistributable (x86) on a 64 bit machine.
Solution - manually install it by going to the log file that is displayed when the setup fails - this appears as a link. Look at the bottom of the text file and it will show the directory of the install file along with other info about the installation failure. Install Microsoft Visual C++ 2008 SP1 Redistributable (x86) by going to the directory shown in the log and installing it.
Error 3:
Install fails when attempting to install Design Review 2012.
Solution - Uncheck the checkbox for Design Review 2012, hope you didn't need it.
