File Transfer

Select 'Read/write access' (or 'Read-only access' if you prefer) to allow access to your local drives. They will appear as 'Other' drives, as below:


SSL Error, Connection Refused

The .ica files downloaded from expire within ~1 minute of download. If you have not launched the desktop within that time frame, you will receive the above error when attempting to connect. To avoid this, have the web browser invoke the Citrix Receiver directly (web browsers will typically allow you to select a program to open a downloaded file) and save this setting. This way, the browser will immediately open the file and avoid any timeout issues.

Cannot start desktop {desktop name}.

This message indicates there are no available desktops to connect to. In an exclusive pool, this will occur if every available desktop has a user logged in. If this error is encountered on an exclusive pool for an extended period or ever encountered in a shared pool, there may be a system problem; please contact

Notes for Linux users

SSL Error

Receiver for Linux ships with its own set of certificates, which may not include the correct certificate for If this problem is occuring, you will receive SSL errors when attempting to launch a desktop. To fix, place this certicate into the directory /opt/Citrix/ICAClient/keystore/cacerts.

Launch from Browser

Disk-Full Errors

As described at the the Windows Systems Overview, the C: drive on Citrix systems has very little available space, and should not be used. However, some programs use the C: drive as temporary storage space, which can cause "Disk Full" errors to appear. Many applications have an setting to control where temporary files are stored – if so, choosing a folder on the S: or L: drive will prevent the error from occurring.

Other applications lack such an option. In this case, another alternative is to copy files to the L: drive and work on them there. As it is local, rather than network, storage, applications may not have to use temporary files. However, as the L: drive is for temporary storage, it is important to copy any changed files back to your U: or G: drive when finished.
