Hi All,
SAP Note no . 865191 for DTW error suggests below
This issue occurs if adodb.dll file is missing in C:\Program Files (x86)\Microsoft.NET\Primary Interop Assemblies\ and/or C:\Windows\assembly.
Please reinstall .Net Framework 4.0 and verifiy that adodb.dll file exists in the above locations. Reinstalling Office Primary Interop Assemblies is
also required in few cases.
Thanks
Deepak
