RAM DataAccess - VBA Error - Class Not Registered

I have created a .xlsm file with some VBA scripts meant to use RAM DataAccess. The scripts are working great for nearly everyone in our office except for one person who is having some weird "Class Not Registered" errors come up when he tries to run the script (screenshot of error below). I blieve the class it is referring to is RAMDATAACCESSLib.RamDataAccess1, but I think that is just because it is the first RAM DataAccess class used in my code. I can't seem to replicate the error on my end and it doesn't really make sense to me since we've already had him make sure his Microsoft Excel and RAM are fully updated. I'm wondering if it has something to do with this similar error mentioned under Bentley's AECOsim section of the website: https://communities.bentley.com/products/building/building_analysis___design/w/building_analysis_and_design__wiki/33771/vba-error---class-not-registered

I'd appreciate it if anyone had some incites into what could be going on here. Thanks!
