My update process works as follows: The application front end has a table which holds the version number. When it starts up the application looks at a particular folder where the most recent version sits and checks if the version number is greater than the one the user is currently running. If there is a new version, the application then calls an existing vbscript which is stored in the same place as the application latest version file. The running, older copy of the application then shuts itself down. The vbscript then checks the folder where the user's copy of the application resides and sits in a loop waiting for the laccdb file to disappear. When that happens the script then copies the new version into place and launches it. If the loop waiting for the lock file to go away takes longer than 60 seconds it gives up and displays a message to the user.

My monster application from WIFI hell has had auto update issues as well as corruption issues. My co-worker that developed part of the app with me wrote an auto update module that Creates a batch file on the fly Closes Access Runs the batch file to copy the new front end to the user's machine and then re-opens access At least that's what's supposed to happen...there have been a number of times that I've been suspicious about whether or not this auto update is somehow triggering back-end corruption too, although I don't know why it would. There have been many times when the app is up and running fine on 10 machines and when the 11th machine starts up and goes into auto-update mode the whole thing comes crashing down. Maybe that's just coincidence. BTW, I'm implementing the 'write to CSV' option today to try and stop the corruption...
