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.
