I pays to do a compact and repair and a compile before you convert.

Open the vb editor window.
Go to debug>compile

Once you have iron out all the errors close the editor window. In the access window find compact and repair (not sure where it is in 2007).
Then create a blank database. Import your database into it.
Convert the new database

It is imperative that you include full Error handling in a Runtime application. The Runtime cannot use the standard Access/VBA error handler, so you must do this yourself. Basically, for every code procedure, you include a line like this:

On Error GoTo Err_Handler

And then further down the line:

Err_Handler:
  '/you handle the error here

There are some 3rd party utilities that can assist you in adding error handling. One of the more popular is mz-tools (www.mz-tools.com), which is free.

BTW: To Compact your db in 2007,  you click the Office button - Manage - Compact.

thanks, makes sense, however did not work.

LSMConsulting:
great lead, I am in the process of adding error trap to every procedure.  I am using the freeware you suggested.

I look forward to it all working.

I will let you guys know if it works.

Used the freeware, set up a micro app with just the area that was causing the problem.

At first I was not getting a trapped or untrapped runtime error in accdb.
Was getting untrapped error in accdr.
Kept cutting away at the code until I found what caused an error in accdr. (still no trapped error message).
Fixed that and reran accdb.  
Got trapped error message. Fixed that and reran in accdr. WORKED.

It seemed i had 2 errors, one masking the other.  i had if/endif with an end in the logic.  
It liked it when i used if/else/endif. the end then was at the end.  Never got trapped error.

The trapped error had to do with rst.close.  It said the object did not exist.  I moved the statement and it worked.

Thanks,
WCG
