Not Able to Pairing Workflow Manager 1.0 with SharePoint 2013

Hi,

After installing workflow Manager 1.0 on a server that is part of the SharePoint 2013 farm, I try to do below steps:

1. Open the SharePoint Management Shell as an administrator.
2. Run below script in Management Shell
   Register-SPWorkflowService –SPSite "http://lcaeengg:47175" –WorkflowHostUri "http://lcaeengg:12291/" –AllowOAuthHttp

Then I got below error:

Register-SPWorkflowService : Could not load file or assembly
'Microsoft.Workflow.Client, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot
find the file specified.

I have tried to uninstall latest version of Workflow Manager Client 1.0, and install a pre-vision which has Microsoft.Workflow.Client 2.0.0.0. But if I do that, workflow host http://lcaeengg:12291/ will return error "Could not load file or assembly 'Microsoft.Workflow.Common, Version=1.0.0.0'".

I have spend several hours on this. Could you help me?
