I have installed EPiServer Community 3.2.0.191 successfully WITHOUT a database (Install site without database - EPiServer Deployment Center).

But when I try to install an SQL database I get the following error:

Error - Exception calling "GenerateUniqueValues" with "0" argument(s): "ServerName does not have a value"

And the Details:

An unhandled error has occured:

ServerName does not have a value

When executing

I have tried to find something about this on the forum and documentation but without any luck.

The DLL-files and EPiServerCommunity folder exists, and I tried to edit web.config adding a connectionString to a new database I created (just so it would point to something) but without any luck either.

Any help would be greatly appreciated!
