JFI ICC color profiles and Capture One 6

I've been using JFI Color Lab's (http://jfilabs.com/) color profiles simulating classic black and white films since version 4 of Capture One. On 64 bit Windows, I place the icc files in the following directory (C:\Windows\System32\spool\drivers\color) and the profiles show up on Capture One if I select a ICC color profile under the "other" menu.

There are 15 color profiles that show up in version 5, but only 14 show up under the menu in version 6 (the tri-x profile is missing). If I review files that I've edited using version 5 and the tri-x icc color profile, then I get the following error message in version 6

"color profile could not be found"

Has anyone else seen this problem of interpreting color profiles in 64 bit version 6 of Capture One?
