Did the same test on a windows machine. Works fine. All the profiles installed by C1 Pro Trial will end up in C:\WINDOWS\SYSTEM32\SPOOL\DRIVERS\COLOR.
C1 LE will see them no problem. Although, if you Uninstall C1 Pro, it will remove also the profiles, something that does not occur in OS X.
Just keep the C1 Pro Trial and use the LE bundle
