You can use Access 2000/2002/XP/2003 to convert it to the JET4 format (mdb).
The converted database can be opened by any later Access version, 2007/2010/2013/2016/2019/365, or converted to the current accdb format.
Access 2000/2002/XP/2003 packages can usually be found on eBay or sites offering second hand licenses.
