This has more to do with Microsoft and especially the 32 to 64 bit conversion than something with Excel I think.

Did you search the web on something like 'conversion .dll 32 bit to 64 bit'?

I found some information, but I'm not sure if this helps you:

Hope this helps, cause I understand it can be a very good solution for your translating. Good luck!

Thank Frans.

It did not help much. Most was too technical to understand.

The dll is actually an excel add-in to be loaded as an automation add-in.

Thank anyway.

OK, sorry to hear it didn't help. I hope one of the more 'technical' people here can help you further. Good luck!
