I don't know exactly how data are stored into DB, so at moment I did only an hypotesis, tell me if I'm wrong or right about that.
I suppose that HikaSerial generates a "product key" associated to user order, and this value is stored into MySql DB, right?
I suppose that into another DB colum another flag value, a "key status", tells me if this "product key" is yet valid or not (suppose that this key is valid only for one year, then user must renew again, and as you told me before user will have a new key when renew)
This way we could build some script to do something like that: those 2 columns (4 maybe with the user ID and user Order) from MySql DB into a MS Access DB (this to avoid final user to connect to MYSql DB and connect to MS Access DB)
Now my excel file could do some check into MS Access to restrict access or not according to key value and "key status".
Is that possible? I mean what data will I find into MySql DB about HikaSerial?
