I was able to get it to launch by navigating to it in the .local/share/tresorit folder and running ./tresorit in a terminal and it seems to be working fine.
If anyone knows how to create a launcher I would appreciate it. thanks
Right Click on the desktop and create a new link to application. Then choose the binary file tresorit in its .local/share/ and choose a description and icon and you should have a .desktop launcher for it.
