*In versions prior and including Ubuntu 10.4 LTS and OpenSUSE 11.2 executing applications from removable devices was/is possible, unfortunately starting with Ubuntu 12.4 the manufacturers decided that its inconvenient for the user to see the message “Do you want to open as executable or to open this file with the appropriate application?” so they simply disabled being able to execute an application from a FAT32 formatted device, like all USB storage devices are.

One of our customers provided us with a workaround, but it doesn’t work for all customers, please visit our support centre and knowledge base.
