I got the error "Setup cannot continue. The Microsoft Runtime DLL installer failed to complete installation".
I read another bloggers suggestion to download the redistributable directly from Microsoft, which almost helped me, but it installed sucessfully, no help there.
However, it gave me an idea, I run the setup, and when the error was on my screen (and before I clicked ok) I could go to my %temp% directory and try to run the vcredist_x64.exe file manually, it gave the error that it couldn't write to D: drive, not enough space. Well, I have a CD-ROM drive in D:, so that doesn't suprise me alot.
I simply swapped my D: and E: drives and fixed my issue, now it installed like a champ, I know this is a workaround, not a fix, but if it happens again I know where to start.
