I found “Citrix 10.1 Rev 3” and “ICA 10” on the Wyse site. I tried installing the rev 3 program as you stated above and on the 2nd install it gives me the option to modify or repair and I chose modify and got the option for the web client but not PNAgent. I uninstalled and tried the ICA10 file but got errors trying to install it.
Not sure if I even have the right msi files at this point.
