Invalid Class String

Hi,

I'm working on both VWDEE and VBEE and, in each, when I try to add a database diagram I get the following message (after the 'Do you want to create required objects' prompt) 'Invalid Class String'.

Any ideas?

Hi,

Do you use SQLServer2000? Do you have the SQLServer 2000 SP4 isntalled? If so, replace the SP4 with SP3a and have a try.

Thanks.

Hi,

The SQL I have is the default express edition that you get with VWD Express Edition, although it shows up in the program menu as 2005 (After installing SQL Server Management Studio Express).

I tried the advice of Salmontraining, in as much as I reinstalled all the express products, and now it works.

So, if you can't get your database diagrams to work, go to control panel/add remove programs and uninstall/reinstall VWD or any of the other Express applications, SQL should be reinstalled automatically.
