Recently, I reformatted my laptop to clean all the junk that Dell installed on it. I thought that everything was in pretty good working order ... this came to halt when I tried to install IIS.

I did usual steps for installing any extra Windows components, Control Panel --> Add Remove Software --> Install Windows Component. I selected IIS from the list and then hit next and then that's when this little guy came up: Setup cannot copy the file staxmem.dll. I was like, WTF? After trying several different methods of installing the component, I finally asked Google. I quickly realized I was not alone in experiencing this problem. I followed one of the links from the post to this KB article. After trying both methods with no success, I realized that that's not the correct fix for this issue. Fortunately, under the same replies there was a reference to this life saver.

Oh the joys of Windows!
