I have a database created in Access 03 for a customer running Vista. The customer is running a runtime version of Access 03. When I make changes to the db and copy them to the customer's pc, the changes do not get copied. If I copy the changes to a pc running XP everything copies just fine. I can copy to Vista if I keep a copy of the old db and create a new name for copied db but that's too much of a pain. Is there a way in Vista to copy and replace a file and get all of the changes? I have even deleted the file on Vista before copying the new file and the changes are still not made. Any ideas from anyone??
