Ahhh, IIS, gotta love it. Nothing can ever be easy.
So, as I am trying to install IIS on my Dell that I just reformatted, I get this:
Cannot find the file STAXMEM.DL_ in my C:i386 dir. hmm….
well, after a little looking, if you run this command
esentutl /p %windir%securitydatabasesecedit.sdb
If you then retry the install, it should work
