To all:  When installing the x64 version on Windows XP Professional x64 (U.S. English), even after a clean boot, when I try to start the application, I am presented with the following dialog box:  "Unable to Query server My Studies:  An error occurred while performing the study root query."

When I click "Ok" the Dr. Watson error reporting window comes up with the following information:  "EventType : clr20r3     P1 : clearcanvas.desktop.executable    
P2 : 1.5.11250.33957     P3 : 4ab2e22b     P4 : system.data.sqlserverce    
P5 : 3.5.1.0     P6 : 486140a5     P7 : 11e     P8 : c    
P9 : system.dllnotfoundexception "

I've tried both the x64 and 32-bit versions and get the same result.

P.S.  I've tried running as Administrator too (even though I am admin on the machine).
