SAP adapter 7.1 issue on the Windows version

I installed WM8.0 on the Windows. But SAP adapter 7.1 cannot be seen on the admin page. The installation document mentioned it happens on Windows becasue of DLL missing. Can anyone tell how to fix the issue in details? Thanks.

1.Go to [FONT=Calibri]: [URL][/URL][/font] vcreadist_**.exe.
3.after install and restart the server.

That must be some requirement from SAP jco.
