Question : Clicking on an ICA file as a regular user does nothing

Hi guys, for some reason, in my Citrix XenApp 4.5 Farm when I click on a ICA file as a normal user nothing happens.  However, if I log in as an Admin it works.  When launching as a user I get no errors or anything, just nothing happens.  The connection manager shows up on the bottom right hand corner and when I open it it just closes.  I tried launching an ICA file from a web interface as well as from the program neighborhood, same issue both times.  Any ideas since this is really killing me?  Thanks!

EDIT:  Just want to mention that I am testing this in on a win2003 Server running XenApp 4.5.  I have a farm of 8 Servers under 1 OU and I am testing by logging into a Server named MF12, trying to open a application located on a Server aamed xenapp1/2

Answer : Clicking on an ICA file as a regular user does nothing

In case anyone else has this problem, deleting the ICA Client reg key on that user and allowing it to re-create it worked.  Turns out my default user profile had messed up settings
