Profile doesn't show up in Photoshop/Windows

I was sent a profile that was built on i1Profiler on a Mac. When it was transferred to Windows, it doesn’t show up in Photoshop. ColorThink Pro doesn’t report any problems. Anyone that can find a reason? …

I don’t see anything wrong with this profile. At first I thought that it might have a different internal name than its external (file) name - but the two are identical. It IS an unusually long name. Perhaps the Windows system is having a hard time with it because of the long file name? My guess is that the problem is in the installation of the profile in Windows, rather than something to do with the profile itself.
