the MSI installer cannot update an previous installation that has been performed using an EXE installer (and vice versa). In such cases you will be asked to uninstall the application manually and to run the installer again. No user data are going to be uninstalled as these are normally stored in user home directories an are not removed during the deinstallation process.

## Disabling Version Notification
|
|
|
|
|
|
By default the application checks the new available version and notifies the user if a newer version is available. These checks can be enabled or disabled by the user.
|
|
|
|
|
|
If you are a system administrator and you run Datovka in a managed environment then you may want to disable the version notification completely (i.e. prohibiting the users from enabling it manually) because the users don't have enough privileges to update the application.
|
|
|
|
|
|
**Since Datovka 4.10.2** there is a mechanism to disable the version notification by setting a special Windows registry value.
|
|
|
|
|
|
The application reads the registry entry `DisableVersionNotification` sequentially in these locations with descending priority:
|
|
|
1. `HKEY_LOCAL_MACHINE\Software\Policies\CZ.NIC\Datovka\`
|
|
|
2. `HKEY_LOCAL_MACHINE\Software\CZ.NIC\Datovka\`
|
|
|
3. `HKEY_CURRENT_USER\Software\CZ.NIC\Datovka\`
|
|
|
|
|
|
If the value is set in multiple locations then the location with the highest priority is preferred.
|
|
|
|
|
|
Datovka on Windows is a 32-bit application. You may therefore need to set values in the `HKEY_LOCAL_MACHINE\Software\WOW6432Node` subtree such as:
|
|
|
* `HKEY_LOCAL_MACHINE\Software\WOW6432Node\Policies\CZ.NIC\Datovka`
|
|
|
* `HKEY_LOCAL_MACHINE\Software\WOW6432Node\CZ.NIC\Datovka`
|
|
|
* `HKEY_CURRENT_USER\Software\WOW6432Node\CZ.NIC\Datovka\`
|
|
|
|
|
|
if you are running 64-bit Windows. For more detail see [here](https://support.microsoft.com/en-us/help/305097/how-to-view-the-system-registry-by-using-64-bit-versions-of-windows).
|
|
|
|
|
|
The value `DisableVersionNotification` should preferably be an integer number with the value of 0 or 1 (or a boolean value), because it is converted to a boolean in the programme. Setting the value `DisableVersionNotification` overrides the values set in the user configuration.
|
|
|
|
|
|
Values of `DisableVersionNotification`:
|
|
|
* **0**/**False** - New version notification is enabled and cannot be disabled in the programme by the user. This value should not be used.
|
|
|
* **1**/**True** - New version notification is disabled and cannot be enabled in the programme by the user.
|
|
|
|
|
|
The application generates a log entry when it tries to read the registry values mentioned above. |
