Using Siebel EAI Transport from Dedicated Siebel Client --

hello guys,
The issue is, we were testing the Siebel 7.7 to weMethods .1 communication (i.e invoking a webMethods test Service via Transport). However it is failing with the error “SystemError 6003: Cannot load dll module “wmISTranport” Error Code: 1233748…” . The testing is done using a Siebel Thick Client (dedicated client) on the consultants workstation. So can Siebel thick client which has it own .cfg and .srf files access wmISTransport.cfg on the Siebel Server or do we need thin client only ?

Using the Siebel Workflow Simulator on thick client, how can one develop and test the integration using wM EAI transport.
