Unable to load DLL 'librfc32.dll' (Exception from HRESULT: 0x8007007E)

Hi!

We would like to hold the account balance data from EMPTOR to SAP and have the following error:

Unable to load DLL 'librfc32.dll' (Exception from HRESULT: 0x8007007E)

We use SAP ERP 2005 on Windows 64 Bit.

Can some one help with the problem?

Thank you very much!

regards

Thom
