The AccdbMerge application includes several executable files. These files are available as shortcuts in the Windows menu, and at first glance, this variety may cause confusion.
AccdbMerge (32-bit) shorcuts are supposed to be used with 32-bit version of Microsoft Access, and AccdbMerge (64-bit) needs to be used with 64-bit Microsoft Access. Otherwise you will get corresponding error message in the database open progress. If none of 32-bit or 64-bit version works and progress displays errors comminicating with Access, then most likely Access component registration is broken and you need to do a full (not quick!) repair of Microsoft Office application.
Compatibility mode shortcuts are useful if any debugger/profiler software is installed on your computer that includes the COR_ENABLE_PROFILING system environment variable. The AccdbMerge application's protection mechanism will prevent it from running in such an environment. Compatibility mode shortcuts disable the COR_ENABLE_PROFILING variable for the AccdbMerge application.
