For a long time I did everything I could to accommodate her, trying to get her systems which would run both the newest stuff she has to get every year and the oldest stuff she has. She is running versions of accounting software that just aren't compatible with anything past Windows XP. This customer has been in business for 20 years and insists that she needs every document she ever produced in the original software she produced it in. I would urge the customer to replace the accounting software now, like it or not, and I'll tell you why.
