I have a relatively new/fresh install of 4.8.2 on a dedicated server.  Tried installing both AD 1.00.00 and 1.00.03 Providers per instructions and get the same errors.

Checked permissions on root directory and subs and web.config.  All appears fine.  Checked web.config <httpModules> section and all appears ok (add name="Authentication" commented out as usual).  Cannot seem to get past this error.  Installs of regular modules goes fine.  Thoughts/Ideas?

No, did not go through the custom install.  Trying to install it after the fact which should still work in theory.  Wish I had installed it during the install process.
