Jun 12 2011 3:31 PM

i made a c# .net 3.5 windows application and then i published the files (including the database file also in the project).
when i install it on pc it gives the error cannot attach database .database with same name exist or it is in UNC etc.
i changed the database name of project to entirely new name .then made appropriate changes.but still it again gives the same error.
