Thank you John for your reply.
You're right, information is needed.
Let's start with the concerns you raise.
The application is "installed" on each machine; Actually how we work is this way; There are several applications - the same modules that are separated into different folders. Each one contains its executable and its pbd's.
In another different folder we have all the DLL's (runtime), and when we run the initial application (menu) it starts in the folder where the DLL's are located.
We are working with computers with Windows7, Windows10 and Windows11.
When an update is released, the executable and the PBD's are copied to their respective folder (this is on a server); and through a third-party program; We update each of the workstations.
Every time an update is made, we ask users to exit the executable and re-enter
Hope this was usefull.
Regards.
If they were using the application, during the update process using the third-party program, the copy (update) might not have occurred.
