Rather old and for older versions of Windows, but check out Adobe - Adobe Color Management Module (CMM) : For Windows : Adobe Color Management Module (CMM) and this forum: Adobe Color Management Modules
There is no 64Bit version of the Adobe CMM it does not exist.
I would suggest you use one of the other CMMs available in PitStop Server, Little CMS is a popular choice.
If you have any issues or questions you can contact me directly or Enfocus support. We have suggested this to our customers who had the same question and have not had any issues reported.
