This was posted in January 2007 - I hope he has found a solution before now :)
The original post isn't clear what the 'issues' are - is he getting an error when running the regasm command, or when running the gacutil command?
The error might be the ProgId he is using, or some other issue.
I'm not familiar at all with the concept of RTD's (RealTimeData?) Presumably he has followed something similar to the example here:

But without more information its virtually impossible to work out what might be the problem.
