3- Decompile Microsoft Access VBA code

When VBA modules get compiled in Access, the complied code is very much dependent on the VBA p-code parser library. There are few types of this library that can lead to corruption if the compiled code is run on various machines with different versions of this library installed.

Microsoft added a command-line switch to access that allows removing all complied VBA codes from an Access database, leaving only the non-complied source code in place. You can try the command line switch if you can gain access into your database but strange error messages will appear during this execution of VBA module/class code.

To run the decompile option from Access just open Access with a command-line option of ‘/decompile’, for example, run the following from the command line:

C:\Program Files\Microsoft Office\Office\MsAccess.exe /decompile C:\DatabasePath\FileName.mdb


You need to change the path shown above for MsAccess.exe if you installed it to a different location. After the completion of the decompile procedure, you should close Access and then re-open it to compile all modules again.
