I'm close to nearly ripping my hair out.
I've installed and uninstalled and re-installed the game twice now.
Every time I get to the last disc and last 1%, Microsoft Visual C++ 2012 pops up to download, but it never starts downloading and gets stuck on initializing (so far I've waited about half an hour and nothing happened).
I have just uninstalled all previous copies I had of C++ in the hope that this time while downloading it won't get stuck.
I have tried downloading the program straight off the Microsoft website but the download doesn't pop up.
Has anyone else had this issue?
This is the retail PC version (which I just paid £40, having lots of fun so far.)
Really appreciate any help.

Thanks for the reply.
For anyone having this issue, what worked for me was uninstalling all previous versions of the software, then reinstalling the most current ones (2012+2013), then when they are installed, go to control panel, click uninstall on them and instead of uninstalling you should be able to click repair. Do that to both of them.
