Citrix Client 10 rollout.

I am rolling out the Citrix 10.0 client to Windows XP Pro desktops & laptops. There are currently 3 earlier versions installed on the desktops. I tested the rollout on a variety or the desktops we use. Everything tested ok except the restart. I have a work-around for that. Out of the 200 PCs I have rolloed it out so far, about 30 or so PCs have had file association issues. When the users tried to open Citrix, it gave them a message that it couldn’t find the app to open the file. It is fixed easey enough by selecting the Citrix folder & the wfica32 file. Is there anything that needs to be added to avoid this issue?
