Because Digita Virtual Office is accessed via the Internet and information travels through an Internet connection, the performance of the software is subject to the same speed variations experienced using the web. For this reason, the bandwidth used when accessing the Internet has a significant impact on the performance of the software.

At a minimum, 128 Kbps for up to four users and 32 Kbps for each additional user should be dedicated to running the Citrix client. To achieve optimal product performance, we recommend at least 64 Kbps per user. Examples of Internet connections that meet these recommendations include dual-channel ISDN, cable modem, ADSL or DSL, T1, and T3.

For the Citrix Client to function properly, the .ica file type must be excluded from antivirus scanning. It is also important that the .ica file extension is associated with the Citrix application in your Windows operating environment. To learn how to associate a file type with a program in Windows, see the Microsoft article Change which programs Windows uses by default .

Additionally, make sure that appropriate permissions are set to the following folders:

• C:\Program Files\Citrix\ICA Client
• C:\Program Files\Citrix\Workspace
• C:\Program Files\VO Citrix
• C:\Users\[username]\AppData\Roaming\ICA Client
• C:\Users\[username]\AppData\Local\Citrix

Because Citrix will occasionally need to communicate with local files and possibly with external storage devices, appropriate session security should be set. You will most likely be prompted automatically to grant security access the first time you launch Citrix. However, if you need to set up access manually, you can use the Citrix Connection Center.

1. In your computer’s Windows system tray, look for the black and white Citrix Workspace icon (you may have to click the Show hidden icons arrow).
2. Right-click the Citrix icon and choose About.
3. On the About Citrix Workspace dialog, click Advanced to expand that menu.
4. Click the Connection Center link.
5. On the Citrix Connection Center dialog, click the name of the server to which you are connected to access the items on the right-hand side under Session Security.
6. Under the drop-down menus for Files and USB/Other Devices, select Full Access and then click Close to save the changes.
7. Click OK to close the About Citrix Workspace dialog.

There are a few known firewall configuration issues that affect performance on Digita Virtual Office:

• F5 – Nagel Algorithm settings
• SonicWall – Deep Packet Inspection settings and or Flexible Packet Inspection Settings

Settings for other hardware and software firewalls may cause similar effects. These should be addressed by a qualified IT professional or product support technicians for the firewall in use.

Printers
During the initial launch of the Citrix client, Citrix searches for and connects to all printers connected to the workstation. The process of auto-creating and mapping printers on Digita Virtual Office servers can be resource intensive. The number of printers installed on your local workstation has a direct impact on the amount of time required to log in to the Digita Virtual Office server. Deleting any unused or test printers will help maintain server responsiveness and improve login times.

To view the printers and devices that are connected to your computer in Windows and learn how to manage them, see the Microsoft article Fix printer problems in Windows 8.1 .

Scanners
You are able to scan into multiple Digita Virtual Office applications using TWAIN redirection built in to the Citrix client. As long you are using a Citrix-compatible scanner with a TWAIN or WIA driver installed, Citrix should be able to recognize and use your connected device.

This issue can sometimes occur in the Digita Virtual Office environment. The application is open, but the window is off screen and not visible on the available monitors. This can be caused by switching from a multiple-monitor to a single-monitor setup between Citrix sessions, or by other related monitor and video card configurations. To resolve this issue, follow these steps:

1. Hold down the Shift key while right-clicking the application on the Windows taskbar.
2. Choose Maximize. This should cause the application to appear on one of the available monitors on your workstation.

On Windows 10, if the above steps do not work:

1. Right-click on your desktop and choose Display settings.
2. Click Display in the menu on the left.
3. Select each monitor and use the Change the size of text, apps, and other items slider to set the same DPI percentage for all monitors.
4. Sign out of Windows and back in.

If the Chrome or Firefox browser window is blank after launching applications through Digita Virtual Office, follow these steps.

• In Chrome
  1. Click the Customize and control Google Chrome button in the upper-right corner of the window and choose Settings.
  2. Click the Show advanced settings link at the bottom of the screen.
  3. In the Privacy section, click the Content settings button.
  4. Scroll to the Plug-ins section and click the Manage individual plug-ins link.
  5. Click the Disable link for Citrix Workspace.
• In Firefox
  1. Choose Tools > Options
  2. Click the Applications tab.
  3. Scroll down to the Citrix ICA client or ICA file content type
  4. Click the drop-down in the Action column and choose Use Citrix (default) or Use Citrix Connection Manager (default).

  

For occasional troubleshooting and other uses, it may be necessary to access Citrix and its Connection Center through your Windows system tray. If the Connection Center icon does not appear in your system tray, follow these steps.

Logging off Citrix is a common troubleshooting step if you are experiencing issues with your Citrix connection. You may need to manually log off when any of your Digita Virtual Office applications have become unresponsive, or if, when trying to launch an application, you receive a message stating that you already have an open session. Follow the steps below to log off Citrix version 14.1:

Login times, as well as data entry and general application performance, are largely dependent on connection latency and bandwidth. You will want to limit unnecessary bandwidth-intensive processes in your office (for example, Internet radio or streaming video) to avoid compromising the quality of your communication with the Digita Virtual Office server. While most websites are static and typically unaffected by intermittent connection fluctuations, Digita Virtual Office applications through Citrix require a persistent connection and thus are much more sensitive to internet issues that would otherwise go unnoticed. Your qualified IT professional and our Support team can assist with running connection tests to help pinpoint possible network connectivity issues.

If data entry is slow in Digita Virtual Office applications, but connection latency and bandwidth appear fine, performance issues may be caused by interference from antivirus or other third-party applications, or by certain firewall settings. Firewalls and antivirus programs have many different settings that can impact performance. For example, if exclusions are not set for local Citrix files and folders, the active scanning of the antivirus application may degrade performance. You should consult with a qualified IT professional to optimize settings for your environment.

In certain situations — usually immediately after an installation of Citrix — you may see an error message when launching a Digita Virtual Office application, or a file may attempt to open in the incorrect application, such as Adobe Reader or Microsoft Edge. In these situations, the .ica file type that Digita Virtual Office uses may not be associated with the correct application. Follow the instructions below to resolve this file association issue.

1. On Windows 8 and Windows 10, press the Windows logo key + X on your keyboard to open the WinX menu.
2. Click Control Panel and then click Default Programs.
3. Click Associate a file type or protocol with a program.
4. In the list of file extensions, select .ica and click the Change program... button in the right-hand corner of the dialog.
5. On Windows 8 and Windows 10, click the More options button at the bottom, and then click Look for another app on this PC.
6. In Windows Explorer, browse to C:\Program Files\Citrix\ICA Client ( C:\Program Files (x86)\... if using a 64-bit machine).
7. In this folder, select the wfcrun32 application file and click Open.
8. You can click OK or Close through the remaining open dialogs to save these changes.
