ActiveX component can't create object, When using .dll/.tlb

Run-time error '429'

I am looking to get a little bit of help with a problem I am seeing. I create a vb.net Class Library that I am calling from VBA in excel. I built the solution and created the .dll and .tlb files. I opened up excel on my computer, VBA Editor, Tools, References, Added the .tlb file, test my vba macro (calling a method in the vb.net class) and everything was working fine. Then, I tried to copy the folder with the .dll and .tlb files to another computer and am having problems. One of the issues is that when i go to add the .tlb to the excel/vba references it never shows up in the list.

Has anyone seen this before?
