Upgrade Your Microsoft Access Database for 64-Bit Compatibility

Convert Access Database to 64-Bit Compatibility

Microsoft is phasing out 32-bit systems, and many businesses are already encountering problems when running older databases in newer Office environments. If you’ve tried to open your database in 64-bit Access and found broken ActiveX controls, VBA Declare errors, or frequent crashes, you’re not alone.

You don’t need to rebuild your entire application. Our consultants specialize in helping organizations convert Access databases from 32-bit to 64-bit quickly and reliably. With decades of experience, we use a proven process to modernize your application, ensure compatibility, and eliminate downtime.

Our 64-Bit Upgrade Process

Our Access 32-bit to 64-bit conversion process is designed to minimize disruption and ensure complete reliability:

  • Database Audit – Identify 32-bit-only code, API calls, or ActiveX dependencies.
