Cannot install/run Toad SS 5

Got the following during install and same if I try to run the app:

Method not found: ‘System.Data.IDbCommand Quest.Toad.Db.IConnection.CreateCommand(System.Data.IDbConnection, System.String, System.Object[])’.
Stack Trace:
at Quest.Toad.Map.MapValidation.IsValidFreeware()
at Quest.Toad.Settings.ToadSettings.SetupDefaults()
at Quest.Toad.StartupForm.Main(String[] args)

I was running Toad SS 4.6 just fine on Friday but this morning it started crashing so I went ahead and updated to 5.

Good morning,

I’ve been trying to synch up two schema copies with 5,000+ tables; and
I get an “out of memory” error on the script build step of the wizard
(with 2395 missing tables to create).

So in my case, that functionality does not work at all.

Is there a way to force the script build to disk, rather than trying to
create it all in RAM?

Thanks, Thomas

This appears to be a very low level error. We have not seen this here before. It
looks like a .net issue.

Please go to your add/remove programs and do a repair on your .net 3.5. Or an


Just want to add that Toad works with .NET 3.5 SP1 version only.

Hello Thomas,

Unfortunately it is a known issue. Can’t find CR number for now…

As workaround I can suggest you to synchronize schemas by smaller portions.
