I have 64-bit Office installed on my Windows 10 64-bit system. This includes Access 2016, 64-bit. I need to examine a simple 32-bit database. When I click on a command button that calls VBA code, I get an error on the first Function it hits telling me I need to mark it with the ptrsafe attribute. Is there a way I can run the 64-bit Access in 32-bit mode? I have downloaded and installed the 32-bit version Microsoft Access database engine 2016 (English), but I don't know how to use it to open the 32-bit database. I don't need the 64-bit Access program so is there a way I can uninstall Access and the re-install the 32-bit version? (I want to leave my 64-bit versions of Office, Excel, Outlook, PowerPoint, etc.).
