Thanks it worked for me too
I'm sorry about the trouble you ran into. Clearing the licenses.licx is fine. This is actually listed in the steps when upgrading from v7.1 to v7.2 in the help - http://help.infragistics.com/Help/NetAdvantage/WPF/2007.2/CLR3.X/html/WPF_Upgrading_Projects_from_NA_WPF_7_1_to_7_2.html.
I got it figured out. I had to delete all entries out of the licenses.licx file. The installation notes said nothing about this. I came across one upgrade doc that was referring to upgrading from 7.1 to 7.2, and all it said was to take out any offending entries. I had seen some offending entries that were causing problems in the compile process, so I removed those. This fixed the compile. There was nothing on the Infragistics forum that addressed this issue. I guess there is something to be said for trial & error & banging you head on the wall. If I’ve introduced problems by deleting the licenses.licx file, please let me know.
