RCP Base plug-in Not found when using smart upgrade for 8.5.1

When upgrading from Lotus Notes 8.5 to 8.5.1 using Smart Upgrade tool I get the following error when I am trying the silent install to install the Single Client Login component.

Using the smart upgrade database I have it pointing to a network share and the following optional arguments are being used.

/v"ADDLOCAL=ClientSingleLogon /lv* c:\temp\install.log SETMULTIUSER=1 SELECTINSTALLFEATURES=SametimeUI /qb+!"

All on one line the result is the user is prompted to upgrade the start the upgrade and part way through the install this error message “RCP Base plug-in not found” is the result

If I use the exact same process and I change the arguments to take out the clientsinglelogon part the install works fine.

/v"/lv* c:\temp\install.log SETMULTIUSER=1 SELECTINSTALLFEATURES=SametimeUI /qb+!"

Using the optional argument line gives a successful install but no client single logon is installed.

If I move the optional arguement to a different part of the line like this:

/v"/lv* c:\temp\install.log SETMULTIUSER=1 ADDLOCAL=ClientSingleLogon SELECTINSTALLFEATURES=SametimeUI /qb+!"

Same error results.

Anyone have any ideas where to place this in the arguement line I found the clientsinglelogon part from the following website.

If anyone can help with this so I can make the silent install include the Client single logon that would be wonderful.

thanks for your time
