MS Access _ File Not Found

Look at the "References".  Were there any connected to the old PC that are not on the new?

No they are both identical in the list.

I reinstalled the "ms activex data objects 2.8 library" to see would that help but nothing

Have you tried to decompile?

Something like this from the "run box":

"C:\Program Files\Microsoft Office\Office\MSACESS.EXE" "C:\users\you\documents\YourDatabase.mdb" /decompile

On checking this again on the PC that is working there is a reference for "Microsoft Access 15.0 Object Library", the new one is 15.0,

I have tried to update it but I am getting a message:

"Cant remove control or reference: in use"

Close out of the database, open while holding the "shift" key.  You should be able to remove it at that time.

I have tried the decompile but it looks like I have wiped all the code, modules wont open and the code behind all command buttons is missing.

I am going to assume that the database got corrupted in the copy.  Try to copy a new version of the file.  Corruption is a big thing with Access databases.

It wont allow me to do that even opening with the shift key held down

See comment 40832786

I have just realise that the the MS Access Version where it is working OK is 32 Bit.

The PC I am moving to has a  64 Bit MS Access version.

Is that what is causing me all the problems?

It very well could be.  Without having access to your environment and your files, it is very difficult to tell.  If you are using different references (even if they are named the same, you might have difficulty).

Is it possible to create a new Access database on the new computer and copy all of the Access Objects in to the new database?

I have transferred a database (accdb) from one PC to another and I keep getting the message "File Not Found".

Lets be clear, ...Is this a split database?

In a split database you don't really "transfer/move" a database.

Each user has a copy of the font end db file on their computer.
The single Back end db file, is typically stored on a shared drive/folder on a server.

Please clarity your setup.

I have tried that I think it is the "Microsoft Access 15.0 Object Library" reference that is missing on the new PC that is making the difference.

Jeffrey, It is an Access 10 accdb file with Mysql BackEnd.

I copied the working file and relinked the tables

ok

I've requested that this question be deleted for the following reason:

I have got completely confused with the questions and as you will see it was months ago and no longer an issue. Apologies for the delay in replying.

Please excuse my ignorance

No worries.  I don't take (nor meant) any offense.
