Hi Philip, perhaps you can help solve my problem as well.
I have been posting in the forums for a few days now and no one has been able to assist me with getting Maya 2015 to install on a Windows 8.1 box in it's entirety. At first I was having the same issues as Ally, it turned out to be an issue with C++. I uninstalled as instructed and attempted to install again, without any C++ versions installed on my machine I was still getting the 1603 error code.
I next attempted to install via the virtual assistant downloads, which worked to get me past the C++ phase (no idea why), but then froze when installing SP2 and would not proceed. I then re-attempted the first method of installation, and luckily it got through installing Maya 2015. Unfortunately however, when it went to show me what had installed, neither DirectConnect or mental ray had installed. After studying each log (attached below) it appears that once again the C++ 1603 error is present, but only in the mental ray and DirectConnect installs.
How in the hell could maya have installed correctly, but mental ray and DirectConnect cannot use that C++ version?!? Maya was only able to install AFTER the virtual assistant (VA) installed the right C++ versions.
It seems for some reason my connection always expires just before installing C++ 2008. The VA version fixed this problem because I assume the VA downloads carry with them the correct C++ version, allowing them to be installed without contacting your network.
Not sure if its a problem with my machine, or your network, or the fact that I'm slowly going crazy trying to get this to install; but regardless, hopefully you can help!
