Tried with "repackage" option and back with the connection manager issue. Is there a way to compare the registry settings of 2 packages other than by hand ?
Finally, got it working, it seems: I repackaged with a fresh W10 VM. I however did have to adujst the "isolation mode" to "Full Access". Otherwise, I could open my DB, but was not able to save changes. Strange DB indeed, only committed when quitting the app and not when a change is made and "treated" .
Next step is to try with the package and the data on DropBox.
Depending on your Data storage settings and Isolation mode, all changes are stored in the changes folder.
•
Data storage: controls where the virtual application places its cache files, and also the isolated changes the application performs.
•
Use either hard disk or USB key, wherever application is launched from (default): if the virtual application's exe is launched from a removable media, the data storage path will be a new directory beneath the executable's directory. Otherwise, if it is launched from the local hard disk (or from an Internet download), it will be stored under the system's Application Data folder.
•
Under the executable's directory: the data storage path will be a new directory beneath the executable's directory.
•
Custom location: any location you wish to specify. See the chapter Path variables. In addition to these variables, a special variable is available for this setting only: %ExeDir%, which means: the executable's directory.
•
Isolation mode: controls whether the virtual application can modify file / registry entries on the target system or not.
•
Isolated (default): the virtual application will not be able to change any files or registry entries on the target machine. Instead, any modification it attempts to do will be redirected to a separate folder or registry key. That folder can be configured by the "Data storage" entry.
•
Full access: the virtual application will be able to change files and registry entries on the target machine.
