A number of people have reported problems installing their paper profiles on Vista. If you are having the same problem try running the EXE file in compatibility mode for XP:

– right-click the exe file
– choose Properties
– click the Compatibility tab
– check the “run this program in compatibility mode for” box
– choose Windows XP
– click OK
– install the profile

– launch Lightroom, go to the Print module, click the Profile drop-down, choose Other, and verify that the correct paper profile is now included.
