After Install - Can I rename the "Install" folder?
 

Dear vBulletin, I have a very simple questions to ask!

I know that after Installing a vB3.8.x we have to delete the "install.php", and after doing that I was also thinking to simply rename the "install" folder!

1: Now what could happen if I changed the name of my "install" folder? And if its possible to change, then do I have to write any lines on my HTACCESS or CONFIG.PHP ?
2: And whats the best way to protect my install folder + all the other folders! And can you please tell me the other folder names that I have to protected?

I have heard about that forums can be brought down or the database can be ruined if someones runs the upgrade.php and using a fake license.
and I have heard lots of ideas about how to Protect the Install folder, and today I use an HTACCESS password to protect it, but I decided to come and ask for some professional help!

Thanks you very much in advance!
