Error running application with Citrix Web Client

After connecting to our Citrix server via the ICA Web Client (version 10.15 but also an earlier version) and launching our application a couple of our customers get the attached "WIFICA32.EXE - Application Error - The instruction at ... referenced memory at '0x0000000c'. The memory could not be read." error.  Both users are running Windows XP - SP2  .  We've tried uninstall/ re-install and reboot.  The error sometimes occurs slighlty sooner after the application launches than other times, and occasionally not at all.  We also tried decreasing screen resolution, to no avail.

Thanks !

IN addition to uninstalling the ICA client, you need to go into each users Profile and remove the application data folder named citrix before reinstalling the client.  Otherwise, any settings that were created in that user's profile will be stored and you will get the same issues.  

One question - is the error on the client machine, or is it coming through from the server session?  UNless the users have administrator rights (I hope not!), it is most likely an error message on the client side, which would reinforce my belief that you need to clear out the stored profile data before reinstalling the client.

The easiest way to test that is to reinstall the client and then log into the machine with a new user and test.

Thanks for the info ...

I'm pretty sure the error is coming from the client.  However, most often our clients do have administrator rights (Windows) on their boxes (in both of these cases they do).  They do not have Citrix admin rights or log in with Windows admin rights on the Citrix server.

Are you referring to the User Profile for Windows on the client side ?  Or to a Citrix profile on the server or the client ?  I'm not sure where this Citrix folder is.

I am referring to the client side profile.

C:\Documents and Settings\<USERNAME>\Local Settings\Application Data - delete the Citrix folder after uninstalling the client, then install the client and try again.

The profile was the issue.  We had an "ICAClient" subfolder (not "Citrix").  Deleteing it and re-installing didn't work, but creating a new user then doing a re-install did for some reason.  Now it also works on the original user.  Go figure.  Anyway, thanks for putting us on the right track !
