For me, removing WebDAV from my server caused the application to return a 503 Service Unavailable Error message when using PUT or DELETE, so I re-installed it back again. I also tried completely removing .NET Framework 4.5 and reinstalling it and also tried re-registering as suggested but to no avail.

I was able to fix this by disabling WebDAV for the individual application pool, this stopped the 'bad module' error when using PUT or DELETE.

Disable WebDAV for Individual App Pool:

1. Click the affected application pool
2. Find WebDAV Authoring Tools in the list
3. Click to open it
4. Click Disable WebDAV in the top right.

Ta daaaa!

I still left the remove items in my web.config file.
