confirmed. full reinstall of 747 without extra liveries all works fine. Installed one livery ------ crash during plane loading. remove livery crash again. uninstall 747 and reinstall again. it work. I think is a pmdg 747 issue with new liveries and operation center

just reinstalled it ( clean install with only PMDG liveries ) again. it work fine. but when i install liveries trough PMDG controll centerfsx it crash during aircraft loading and this with any liveries. If i try to uninstall liveries except Pmdg liveries it crash again. the only way to do is a full unistall and a reinstallation without adding liveries. An other issue is with Norton antivirus and pmdg product . Norton recognized every pmdg product dll as a virus . i suggest to deactivate antivirus during simulation. in ex it block 777 aircraft loading and crash FSX. if i disable Norton the aircraft is loaded. I've tried to exclude Norton scanning for pmdg product but every time it recognized PMDG's as a threat.
