Well, for those who need to uninstall a Citrix client from one or all computers on the network, be it a current customer or an old one to replace it with a new one if possible personalized (We can be guided by this: HTTP://www.bujarra.com/?p=676), there is a utility from a friend of mine called UNICA de Gourami that is totally free and runs by command line. With this program we will be able to uninstall any version of the Citrix client from the version 4.0 to the current one 11.0 o XenApp Plugin. Apart from putting parameters to the command we can put the file to install after a successful uninstallation, another parameter to put a message while performing the process and another to generate a LOG file with the information of what happens.
