So I'm getting ready to do some work with Laravel Homestead, and was following all the installation instructions, and everything was running smoothly until this came up:

And then so I went to the link provided at http://www.microsoft.com/download/en/details.aspx?id=5582

After I downloaded what was required, I then got this message, as seen in the picture below:
Why is it asking to repair or uninstall Microsoft Visual C++ 2008 Redistributable??....I'm afraid of selecting the wrong option!!
One option is to reinstall visual c++ or if it doesn't work install a different version of visual c++ and select appropriate version of xampp that runs with it.
I personally downloaded latest version of xampp that runs with visual c ++. 2015 and for days I lost sleep getting dll error. Then I installed visual c ++ 2008 and a lower version of xampp and it worked.
Make sure you select PHP version 5.2 and above for oops. Make sure you select 32 bit (x86) for visual c++ even if u r using 64 bit computer because xampp runs only in visual c++ 32 bit version. Also download service pack 1 from Windows site and update Windows OS using it. I think that will solve the problem.
