I know this thread is old, but in the absence of any updates from xRite on this issue (can't believe how long it takes them to fix really major problems

), and also the need to make some more profiles, I thought I'd follow Doug's suggestion and try un-installing i1Profiler 1.7.1 and doing a complete re-install of 1.7.1. It works - the "Print" button now functions properly! Not sure why this un-install/re-install fixes it, but I wanted to confirm that it is worth doing if you are using 1.7.1 on Windows and want to print your profile targets directly from i1Profiler rather than use ACPU.
