General Installation Instructions

To install this ePad System Software, Download the software from our website and follow the instructions to complete the installation of the ePad software.  

Silent or Unattended Installation

Installation can be automated by using response files. To generate a response file, run setup.exe on a typical target machine as follows:

** These commands should be typed into a command prompt window or the Windows Run dialog (accessible by clicking Start --> Run). Replace <full_path_to_setup> with the fully qualified path and file name where setup.exe is located (e.g., d:\setup.exe). Replace <full_path_to_response_file> with the fully qualified path and file name where the response file is to be created/read from (e.g., c:\response.in).

<full_path_to_setup> /r /f1"<full_path_to_response_file>"

Configure the installation as you want all targets to be configured. When setup completes successfully it will create the response file at the location specified.

To run the installer silently, issue the following command on the client machine(s) (this assumes you've copied setup.exe and the generated response file to the client):

<full_path_to_setup> /s /f1"<full_path_to_response_file>"


Terminal Server and Citrix Support

l   On Windows 2003, go to control panel, click on the “Add or Remove Programs” icon, press the “Add New Programs” icon from left panel, press the “CD or Floppy” button to install ePad Software

l   On Windows 2008, 2012 go to control panel, viewed by small icons, click on the “Install Application on Remote Desktop…” icon and follow the instructions on the wizard to install ePad Software.

In the event you wish to manually enable support for Terminal Services, the following procedures can be used:

ePad provider names, folder names, and file names

Terminal Services may be manually configured for the following ePad products by using the file names designated:

Provider Name

Key Name

File Name

ePad USB



ePad-ink USB









Server Installation

  1. Install the ePad Software
  2. Create the following registry folder:

HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\AddIns\<Key Name>

  1. Create the following keys / values within this new folder:

REG_SZ,Name,<File Name>

Client Installation

For the client, the Citrix/Terminal Services client software is required. Download and install the 11.2 client software.

Installation on Wyse XP Embedded Terminals

When installing the ePad software onto an XPe terminal, the following guidelines must be followed:

·         Must have Administrator access
Thin clients are typically configured with a limited user account (User) and an Administrator account. To log on as Administrator, hold down the shift key and log-off User.

·         Installation package must be accessible via network
Since the Wyse thin client has no CD drive, the only means for obtaining the Universal Installer is via a drive mapping on the network. Therefore, the installer should be placed in a folder accessible by the thin client.

·         Temp directory must have sufficient free space
Since the installation package is unpacked to the Temp directory, the Temp directory must have enough space for the intermediate files. The Temp folder is oftentimes drive Z:, which is a small RAMDisk. To ensure that the Temp folder is large enough, create a new Temp directory on the C: drive (C:\Temp) and change the 'TEMP' environment variable to point to the new directory. To change the environment variable:

    1. Open the Windows Control Panel
    2. Double click the System icon
    3. Select the Advanced tab on the System Properties dialog
    4. Click the Environment Variables tab
    5. In the System variables list, select 'TEMP' and then click the Edit button
    6. Enter the new value and click OK button
    7. Click the OK button on each open dialog to save the changes

·         The Enhanced Write Filter should be disabled
There is an Enhanced Write Filter Control utility as part of the Wyse thin clients. This program monitors system resources and when a threshold is reached, automatically reboots the system. After rebooting, all the changes that had taken place since the last logon are rolled back. Therefore, if the software installation is to be permanent, the EWF must be disabled before running the ePad software installer.

During installation, select the Custom setup. Select the appropriate ePad devices as well as MS Terminal Services and/or Citrix client options as necessary.


Map Inking Region Only (ePad-ink)

This option will result in data only being reported within the specified inking region of the device. The data is rescaled so that unity is within this region. Note that no data reports will occur outside this region when this option is enabled.


ePad-vision Images

The ePad-vision has the ability to store up to ten screensaver images and one signature background image in its memory. These images can be managed via the ePad-vision Control Panel, which can be found in the Windows Control Panel. ePadLink recommends using images that are sized to 480 x 272 pixels to avoid distorting the images appearance on the device.


ePad-vision Downloadable Font

The ePad-vision has the ability to store up to twenty-five System Independent Format (SIF) fonts in its external memory (Flash or RAM). SIF fonts can be created using the FontGen.exe program located at the ePad/Tools/ePad-vision folder. These SIF fonts can be managed via the ePad-vision Control Panel, which can be found in the Windows Control Panel.  Please refer to the Local Font Manager User Manual at the Tools/ePad-vision folder for detailed instructions.


Known Issues

  • ePad-ink "Disappears" Off Of the USB Bus

In firmware versions 1.00 and earlier contact with the touchscreen while performing I/O to the device (such as transferring a background image) may result in the device failing to respond over the USB bus. The end result is that device functionality will be lost. To recover:

    1. Reboot the system.


    1. Close all programs.
    2. Detach the device.
    3. Reattach the device.


  • ePad-ink Display May Not Clear When the Computer Is Shut Down or Restarted

If the computer is shut down or restarted while an application is using an ePad-ink unit, the display may not be cleared. The display should be refreshed the next time an application initializes it or it can be manually cleared by unplugging the unit and then plugging it back in.

  • ePad-ink May Fail to Open on Some Computers

On at least some HP / Compaq PC's we have observed that the process EAUSBKBD.EXE will open the ePad-ink preventing our system software from using our own pad. The solution to this is to:

    1. Terminate EAUSBKBD.EXE (using the task manager)
    2. Prevent EAUSBKBD.EXE from running to begin with by either uninstalling or by modifying the system's configuration settings


  • Cannot Set Screensaver Option During Initialization (ePad-ink)

The screensaver option fails when attempting to set it while initializing the pad. To change the default screensaver behavior, set the option after the pad has been initialized.

  • Cannot Sign on the ePad device over Windows 8.1

Since Windows 8.1, Microsoft has introduced a new power management method for USB devices to reduce power consumption on mobile computers. This approach may suspend the ePad device or show delay on signature capture. To solve this issue, the SetPowerManageField.exe, located in the ePadLink/ePad folder, may set the EnhancedPowerManagementEnabled field in the registry with proper value then reset the device to apply the changes made in registry.
