install assembly into GAC

Jul 23, 2007 at 4:06 AM
I tried copying the assembly into "c:\windows\assembly", but after that I start a workflow in the desginer2007.
"The list of workflow actions on the server references an assembly that does not exist. Some actions will not be available. The assembly strong name is DP.Sharepoint.Workflow, Version=1.0.0.0, Culture=neutral, PublicKeyToken=0298457208daed83. Contact your server admin for more information."

Then I tried to install using gacutil.exe
But
"Failure adding assembly to the cache: Unknown Error"

I need help to install this assembly.
Thanks.

I have the same problem.

Even after the assembly is installed in GAC using gacutil.exe, i get the error while createing new workflow in sharepoint designer:
list of workflow actions on the server references an assembly that does not exist. Some actions will not be available. The assembly strong name is DP.Sharepoint.Workflow, Version=1.0.0.0, Culture=neutral, PublicKeyToken=0298457208daed83. Contact your server admin for more information."

I have the same issue... but I only get this issue on one site. All my other sites work fine.

Does anyone know how to fix this?
