Install w/o Bitnami support

Hello community,
I found a small problem that creates problems for inattentive like me.
The presence of SQL Lite is a system REQUIREMENT even if you do not use SQL lite.
When it is not found, launching the second time the setup, does not complete and creates the white page error. Even if you use one other Db.
This was the first problem with IIS (but I've seen threads with the same problem in Apache).
I solved the problem installing and enabling SQL Lite 3 (a very little work on config files).
Now, the main problem...
The row
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
is needed to handle the authorizations and it does NOT work in IIS. The rule can't be imported because IIS URLS rewrite does not support the flag "E".
Instead you need to work with Rewrite maps and more complex rules. Unfortunately I do not have the necessary knowledge to do so. I'll ask one of the guys on my team, more experienced, to help me when he can.
At the moment, I am at the login screen and the system is answering correctly (but the REST answers with a "not authorized" message when I log in).
