After EXHAUSTING hours and hours...I can say I have the EXACT SOLUTION to everyone's Visual c++ 2013 refusal to install and preventing Acid to setup.
You MUST only have MS Visual C++ 2013 x64 AND x86 versions 12.0.30501 installed in your Windows. ANY other versions have to go for 2013 c++'s(uninstall them all if different)...if you need to download versions 12.0.30501...here is a link:
install both x86 and x64 for 30501. Like I said-for 2013, there should be NO OTHER versions.
I guarantee you this works. It WILL install if you do this!!!! I am pleased to aid all who have banged their heads against the walls....Believe me, I've been there.
