We have an old .mdb database on our internal network used to collect defect information. This has been working fine at all computers through our plant. Our IT department regularly replaces old computers with new ones, the new ones have Access 2013. One of these new computers has the 32-bit version of Access, this database works fine on that machine. The other are the 64-bit version, when I open the database with this version the command buttons on the main switchboard will display but the events associated with them will not fire, nothing happens. I did convert a copy of the database to .accdb and opened it with the 64-bit Access 2013 but the command buttons still did not work. Any suggestions?
