Unable to update database .MDF is Read Only

Question

I have a local DB that I have in an application. When I install it on another machine I get the error

Unable to update database.. .mdf is read only.<

Answer 1

First stop the SQLEXPRESS service from local-Services menu and then try to move and connect the database again by attaching database option in SQLEXPRESS. it should work. it works for me. :)
