Devart Forums

Hi,

Installation of the trial version went well (dotConnect and SSIS Data Components). I can create a connection which tests ok. But it doesn't show in the source component. There I try to create a new connection. But then I get following error: Unable to cast object of type 'Devart.Data.Salesforce.g' to type 'Devart.Data.Salesforce.b1'. Please some assistance! Many thanks in advance.

The reason of the error is that two different versions of the same assembly are used at the same time.

You have installed dotConnect for Salesforce Trial and SSIS Data Flow Components Trial on the same computer. These products use different Devart.Data.Salesforce.dll assembly versions. Uninstall both products and then install only one of them.

Is the issue reproduced when only one product is installed?

Thanks, Pinturiccio. It works now with only dotconnect.

BR, Steven.
