I'm trying to use an excel add-in that comes with a custom developed DLL for calculations which is usually stored in my windows/system32 directory.

Can I still reference the file from my excel vba without storing in windows/system 32?

For example, I tried to register it manually based on storing it in another location using the regsvr32 command but I was unsuccessful with the message “the file was loaded but the DLL register server entry point was not found”

Could I use code to open/reference/activate the file by placing it in another location (e.g. the folder where the addin is stored)?


I am not a progammer, just know some basic VBA for excel so really hope someone can help.

Thanks,

Nick
