Personal Free Edition will lock the file when project to other PC, so I make decision to unlock file after registration with configuration form, When you want project to be on other PC, please use Personal Free Edition to save and personal meaning to move project. The standard edition of project files are isolated and only Personal Edition verson save as with FType = 3 to open project in other PC. I said this new to users and let users to know the situation will be security and safty to development. Standard Edition use FType = 4 will be isolated the lib and without confirmed code will not open the projects correctly and maybe it is incorrect data and diagram.

Please Install Personal Free Edition and Standard Edition with your decision and make security for your development. Free edition can release project to other PC make you personal file access.
