find the version of windows your running, download the package for that version and install.
If you don't want to click that link, then just go to microsoft.com, go to support, search
"missing api-ms-win-core-localization-l1-2-1.dll Windows 7" (change the 7 to the version of windows you have), if you use the above search term, the very first link is the one you want (also the link posted above), and again once in there just find your windows version down load it and install.
