Upgraded to Mageia 5 from 4 on 64 Bits and ruined Citrix.
The latest version for Citrix was 13.1
Citrix just released version 13.2
Followed the same steps as I did before for version 13.1
What I did was Remove the old one via command... ./setupwfc
Answered the questions for removal and used the defaults.
Downloaded the new version and within the directory typed... tar xvf linuxx64-13.2.0.322243.tar.gz
Ran command from the un-archived directory... ./setupwfc
Answered the questions and used the defaults.
On Firefox went to Preferences>Applications> and choose Use Critix Receiver Engine (default)
And that worked for me.
