Hello all, I'm currently running NXLog Enterprise in Version nxlog-4.0.3550-x64 with the following config: Module im_msvistalog File C:\logs\Security.evtx Module im_msvistalog File C:\logs\Application.evtx Trying to read-in from 2 local evtx files. In the nxlog.log I see the following error: 2019-01-21 14:34:33 ERROR ### ASSERTION FAILED at line 1945 in im_msvistalog.c/im_msvistalog_start(): "((nx_im_msvistalog_subscr_t **)(imconf->q_subs->elts))[imconf->q_subs->nelts-1]->query = imconf->_query" ### 2019-01-21 14:34:36 ERROR last message repeated 4 times 2019-01-21 14:34:36 ERROR ### ASSERTION FAILED at line 1945 in im_msvistalog.c/im_msvistalog_start(): "((nx_im_msvistalog_subscr_t **)(imconf->q_subs->elts))[imconf->q_subs->nelts-1]->query = imconf->_query" ### Do you know what I'm doing wrong here? From what I've read in the manual, the enterprise edition should be able to read evtx files. best regards, micsnare
