Failed to connect to the SQL database SSODB

If we are experimenting problems with SSODB in our development environment and we have the following entries at the event viewer:

Could not create SSOSQL. To fix the problem, reinstall SSO or try 'regasm SSOSQL.dll' from a Visual Studio command prompt. Error Code: 0x80131700
OR
The SSO service failed to start. Error Code: 0x80131700

We have to execute the following command:
regasm %Program Files%\Common Files\Enterprise Single Sign-On\SSOSQL.dll
