Problem with patch add-on

Hello All,

We have CRM 7.4 installation.

I had Install the Desktop Connection add-on component CRMGWS 700: by using SAINT. Now I try to patch this component by:
CRMGWS 700: Support Package 0005.

I'm currently using a SAINT transaction in SAP Basis. The .SAR file is decompressed and a .PAT file is .../EPS/IN directory, The SANIT I had load package from Applican server.

but it is not listed on the screen for the add-on selection. As such, I cannot continue with the installation.

Any Idea how can I patch add-on on CRM?

Thanks for any advice.
