[THIN] ICA won't launch

I think I posted on this before, but I have a client who still cannot launch the ICA files.
I have taken the following steps to no avail
He is running XP SP2 and IE6


1) Un-installed web client and re-installed with Full PN client (version 11)
2) Cleared Temp files in IE.
3) Unchecked "Do not save encrypted files to disk
4) Cleared the HLKM/software/Microsoft/MSLicensing/Store?license00x keys
5) Run wfica32.exe /setup
6) Removed Google and Yahoo Toolbars.
7) Double checked file associations.

I have tried right-clicking and saving the ICA file, then launching it manually.  Still no luck
I think next I will try an exorcism.
