Quartus 17.1 Lite Launch Crash on XUbuntu 14.04

[Altera_Forum]

Hello everyone, 

I installed Quartus recently on a Linux machine in my University. The installation completed without problem and I can launch the program without any problems if I am logged in as administrator. If I launch Quartus as guest User it crashes instantly and the Report stats:  Problem Details Error:   *** Fatal Error: Segment Violation at (nil) Module: quartus Stack Trace:  0xe0a80: Ox3476f84b43216cbb + 0x50 (sys_cpt)    0xb28a8: Ox3476f8367c6535b1 + 0xc8 (sys_cpt)    0xa3b47: lc_getid_type + 0x57 (sys_cpt)  0x560d3: cpt_flexlm_get_local_hostid_by_type + 0x5e (sys_cpt)  0x56224: cpt_flexlm_get_local_hostid + 0x13 (sys_cpt)  0x395e1: CPT_FLEXLM_MGR::get_local_hostid(CPT_HOSTID_TYPE, std::vector<std::string, std::allocator<std::string> >*) + 0x41 (sys_cpt)  0x3d8be: CPT_MANAGER::get_local_hostid(CPT_HOSTID_TYPE, std::vector<std::string, std::allocator<std::string> >*) + 0xa6 (sys_cpt)  0x18507: cpt_guiq_append_url_args(std::string&) + 0x1eb (sys_cpt_guiq)  0x18dd5: cpt_guiq_ping_web_edition_tracker() + 0x21 (sys_cpt_guiq)  0xba1b: cpt_guiq_dyn_init + 0x1bb (sys_cpt_guiq)  0x6829e: QUI_APP::init_instance(int, char const**, QUI_CMDLINE*) + 0x3ec (sys_qui)  0x1202d: QGQ_APP::init_instance(int, char const**, QUI_CMDLINE*) + 0xdf (sys_qgq)  0x1e9f: qgq_main(int, char const**) + 0x5f (quartus)  0x40720: msg_main_thread(void*) + 0x10 (ccl_msg)  0x602c: thr_final_wrapper + 0xc (ccl_thr)  0x407df: msg_thread_wrapper(void* (*)(void*), void*) + 0x62 (ccl_msg)  0xa559: mem_thread_wrapper(void* (*)(void*), void*) + 0x99 (ccl_mem)  0x8f92: err_thread_wrapper(void* (*)(void*), void*) + 0x27 (ccl_err)  0x63f2: thr_thread_wrapper + 0x15 (ccl_thr)  0x427e2: msg_exe_main(int, char const**, int (*)(int, char const**)) + 0xa3 (ccl_msg)  0x1f7a: main + 0x26 (quartus)  0x21ec5: __libc_start_main + 0xf5 (c.so.6)     End-trace  I'm thinking that it might be permission related, although I checked and the permissions seem to be the same with Quartus as with programs that run as guest. But I am not 100% sure because I am not too confident with linux. Quartus 13.1 Lite is also installed, and it works fine. Maybe one of you guys know a solution.
