LUapps provides virtual access to software installed and running on servers in Lehigh's data centers.  These applications are available via the Citrix Workspace client and can only be accessed while connected to the campus network.  Remote access is available via the Lehigh VPN.

How To:

How do I install LUapps on different devices?

See this Getting Started document.

How do I upload a file to Course Site from within LUapps?

See this document: How to Upload a file to Course Site.

How do I reset file access permissions in the Citrix Receiver (Mac OS)?

See this document: Resetting Access Permissions in Citrix Receiver

How do I access LUapps on a Chromebook?

  1. Install the Chrome extension for the Citrix Workspace app via the Google Chrome Web Store:
  2. After installing, go to the LUapps website ( and login with your Lehigh credentials
  3. Clicking on an application may open the application or simply download a file to your Chromebook–if a file is downloaded, double-click the file to launch the application

Where do files get saved?

This depends a lot on the particular app you're using, but generally, look for files to be saved in the 'VirtualFiles' folder in your H-drive.  The H-drive is backed up several times a day using two different methods, and is accessible both on-campus, and over the internet using the VPN. If you're using a Windows or macOS computer, you can also save files to your local computer -- see 'Finding and Saving Files in LUapps (Citrix)'

How do I access a departmental file server from a Citrix app?

If you have access to a departmental file server, and want to access those files from within Citrix, there are two methods.  

The best method is to use Lehigh's Kumo service, which allows you to set drive mappings for various services (including cloud storage services) as well as local file servers.  Since it's handled directly by the server, it's much faster.

You should map a drive to the file server with your computer before connecting to Citrix, and access it as a 'client drive'.  Once connected, your mapped drive will appear as a 'client drive' in the storage options list.  In the list the name will be followed by text in the format '(<drive letter> on <client computer name>)'.  Since information sent over this connection has to travel across your network connection and back to the server, it's much slower.

How long can I stay logged into LUapps?

For students, an active session stays connected for a maximum of 12 hours, for faculty and staff, 24 hours.  Your session will be automatically disconnected once you reach your limit even if you are actively using the application.  Please consider a local installation or contact your Computing Consultant if you need to run applications for longer periods.

How long can my LUapps session be idle before it is disconnected?

Your session will remain active for 2 hours without user input before it is automatically disconnected.  Feel free to grab a beverage or a bite to eat as long as you can do it within 2 hours.

What's the Citrix Workspace?

Citrix has a slightly different application for connecting called 'Workspace'.  The functionality is largely the same with some feature improvements and other add-ons.


My session keeps freezing. I log out but when I log back in the system returns to the same frozen session.

Contact the LTS Help Desk at 610.758.4357 to have your session unlocked. 

I can't find the file on my hard drive when I'm in LUapps.

Learn how to Finding and Saving Files on LUapps (Citrix).

I get the error message "The system cannot find the path specified. This working directory is invalid: h:\"

Go to and log in. Choose the option to Reset H drive permissions. You'll see a message that "The repair operation has been initiated for XXXXXXX." Try logging into LUApps and launching the application (this should resolve the issue). 

When I try to load an application, nothing happens.

You will need to install the Citrix Workspace application.   Instructions for installing on the macOS, Windows, Linux, iOS, Android are on the web site. Click on the highlighted link that matches your OS to go directly there.

How do I 'Unblock the Citrix plug-in'?

If you find yourself at a LUapps screen like this:

You'll need to quit and re-open your browser.  When you navigate back to '', you should be asked whether to 'Trust' luapps to use the Citrix Receiver plugin:

Click 'Trust' and you should get to the 'StoreFront' with all of the apps.

I keep getting pop-ups about Citrix Receiver not being 'optimized' for my operating system. What's that about?

Currently, the Citrix Receiver client for macOS is written using 32-bit code libraries.  macOS is a 64-bit operating system, and recommends developers update their code to make use of that.  Hopefully, a future update will address this.

Do I need to get a patch for the Citrix Receiver on my Mac?

In the short term, it's not a huge concern, but going forward, you would benefit from the available patch.  The macOS version of the Citrix Receiver client's mechanism for updating automatically when you connect to the server doesn't function, and the patch allows it to do so.  The security of the client software is the biggest concern, and having the most up-to-date version installed is the best practice.  It's available from the Citrix website, and you can download and install it following their instructions.

I got a message asking 'How do you want to access files from this application'. What should I say?

You can control the Citrix Receiver application's ability to access files on your computer.  To start, it asks you what you want to do with a pop-up like this:

You should generally respond with 'Read and Write' so that you can both open files from your computer and save files there too, if you need to.  

If you want to change whatever setting you picked, you can go to the preferences for 'Citrix Receiver' and re-set them.  This is fairly easy in macOS.  It's more involved in Windows, so we recommend getting LTS assistance with that.

I'm on-campus, but still can't connect to LUapps. What could be wrong?

The 'lehigh-guest' network is designed to provide short-duration access to the Internet for visitors to Lehigh who do not have a Lehigh Computer Account. Students, faculty, and staff should not use it.

To LUapps, this connection is considered an off-campus network. If you cannot connect to LUapps, even after installing the Citrix Receiver, it could be because you are using the 'lehigh-guest' network. LUapps requires the use of either a hardwire connection to the campus network, or a connection to the 'lehigh' network.

Follow these instructions to connect to the 'lehigh' wireless network.
