The LUapps software virtualization system can be a bit complex to understand and use effectively. Below are a few answers to questions you may encounter when using the system.
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 'Open and Save Files in the Citrix Environment (LUapps)'Back to Questions
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 'https://luapps.lehigh.edu', 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.Back to Questions
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.Back to Questions
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.Back to Questions
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 assitance with that.Back to Questions
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 'lehigh.'

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 fomat '(<drive letter> on <client computer name>)'.Back to Questions
An active session stays connected for a maximum of 12 hours. Your session will be automatically disconnected once you reach 12 hours even if you are actively using the application.
