Umbraco + YAF integration - connection issues

I'm working to try and get a migrated Umbraco/YAF installation working, but I'm having issues with connectivity.

I've already asked for help with the Connection Strings, so this bit is sorted.

However, I still get a 404 error when I try and navigate to mysite/forums, as it redirects to mysite/install

This site tells me that this could be because of a few issues:

It will connect you to install\default.aspx if 
: its connect to a db but thinks there isn't a YAF version present in its data, or
: database version doesn't match 开发者_如何学Goand thinks it needs updating.

I know it's connecting to the DB, because the CMS connection string works, and it's connecting to the same database.

There are YAF_* tables in the database, so I know it's content is there.

By process of elimination, it might be a version issue, but I'm not sure how to compare the DB version to the ASP files version.

I'm running Umbraco 4.6.1

I never quite worked out what version I was running, but I did find out this issue was fixed by:

Assign yaf database user db-owner privileges. 

And there you have it.

check that you have the following line in web.config

<add key="umbracoConfigurationStatus" value="4.6.1" />
