KB-000400: When installing the Impatica Docking Station application on my BlackBerry, I get an error stating that the digital signatures are invalid. What does that mean?

You will see this error if your BlackBerry IT policy has "Disallow Third Party Application Downloads" set to TRUE OR "Allow third party application downloads"—Set to FALSE; (Phrasing is dependant on BES version). Please check with your BlackBerry Enterprise Server administrator for details on this IT policy.

The error looks like this:

The IT Policies and Application Permissions required for the Impatica Docking Station to work are outline under section two on this page:

Here they are for your convenience:

Once you have installed the application, you must ensure that the necessary application settings and IT policies are set:

IT Policies:

For Bluetooth communication (under the Bluetooth policy section of the BES IT Policy dialog box):

    • Disable Serial Port Profile—Set to FALSE
    • Disable Bluetooth—Set to FALSE
    • Disable Pairing—Set to FALSE

For USB communication:

    • Allow third party applications to use serial port—Set to TRUE

For over-the-air installation:

    • Disallow third party application downloads—Set to FALSE (Phrasing is dependant on BES version)
    • Allow third party application downloads—Set to TRUE (Phrasing is dependant on BES version)

Application Permissions:

In order to use the Impatica Virtual Dock, you must ensure that your application settings are properly configured by performing the following steps:

a.    Navigate to Options > Security Options > Application Permissions

b.    Select Impatica Docking Station from the list

c.    Select Edit Permissions, then either:

(a) set all items under Connections and Interactions to Allow; OR

(b) set the following specific permissions to Allow:

                                                  i.    Under Connections:

1.    USB (only if USB connection is required)

2.    Bluetooth (only if Bluetooth connection is required)

3.    Phone

           ii.    Under Interactions:

1.    Interprocess Communication

2.    Keystroke Injection

3.    Screen Capturing

Note: If your BlackBerry is associated with a BlackBerry Enterprise Server ("BES") or ever has been associated with a BES, you may not be able to change the application permissions. In that case, an application control policy would need to be set on your BES and the Impatica Docking Station applications would have to be pushed to the device with these settings set to Allow.
