My index.html wont show up when i have wordpress installed in sub directory

Hi,

This’s what i wanna do, having static HTML with wordpress files.

/index.html ---> showing static index.html as my top page for my site
/about.html ---> static.html
/feature.html ---> static.html
/wp/ ----> the subdirectory for wordpress, where the wordpress is installed.

I would like my HTML to execute PHP, so this’s my .htaccess under /

AddType application/x-httpd-php .htm .html

And this’s the .htaccess under wp/

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wp/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wp/index.php [L]
</IfModule>

# END WordPress

I cant see anything wrong here, but when i access to my site,
https://localhost/
it keeps giving me 404 error, and redirecting me to:
https://localhost/wp-admin/install.php

There’s no wp-admin/ under /
Where is the mistake here?

If i delete the .htaccess under /, the page shows up well.

Thank you.
