automatic change of permission on database after install web site

I have Web Site with ASPNETDB database and own database. I was precompiled this site and I created aplication with Web Setup Project. This setup aplication includes SQL 2005 EXPRESS. When I installed and ran an my web site in Internet explorer, that displayed error "Failed to update database ... because the database is read-only". I know, that is a bug with permisson and the fix a bug is solution for this problem but i have installation package and i need automatic fix in setup application. Thanx for comments.

Vitty,

The main focus of this forum is on connectivty, client odbc/oledb drivers and etc. The expert on your issue might not visit this forum often. So, I suggest you to visite sql setup forum instead.
