Thank you for reading.
I tried to install BuddyPress as Plugin in my existing WordPress and its working. My problem is the theme is not compatible for BuddyPress. Even though there’s a BuddyPress Template Pack plugin, the theme is useless for BuddyPress. What I need right now is a Premium WordPress Theme compatible with BuddyPress.
I will remove the BuddyPress in my the other folder (community) and will look for the theme instead.
Thanks for the help!
Or enable the network:

Then click the “add site” button to make /community/. Activate buddypress there. put your buddypress theme on that blog. Problem solved.
To install BuddyPress on a secondary blog, you can also read this:

If you’re looking for a matching BP theme for your WordPress theme, currently BP Template Pack is the only plugin in town and it needs updating.
A premium theme with BP support built-in is the other alternative like you stated.
