Thank you for your posting. The only known issue that may a factor here related to versions of Formativ Runtime prior to build 184.108.40.206. With earlier builds, an access violation could occur on shutdown due to an interaction with the Microsoft Script host debugger. The fix was to install a version 220.127.116.11 or newer.
If this does not solve your issue, I would suggest you uninstall Formativ, manually delete any files left over in the ‘C:Program FilesAdvansysFormativ’ folder, then re-install.
