Dear Friends,

As i am using captaris workflow 6.5 and share point server 2007.

workflow is in one server and share point is in another server.  i have installed sharepoint integration component in the share point server.

When i am trying to add workflow webpart to share point portal,it is giving the following error.

I do not believe this is a Workflow issue as much as a sharepoint security issue.

I suggest you amend the
security policy file so that UnsafeSaveOnGet's are allowed, like this:

                            <IPermission class="SharePointPermission"
                                    version="1"
                                    ObjectModel="True"
                                    UnsafeSaveOnGet="True"
                            />  

Remember to reset IIS after making the change.
