Chris71 It is important to note, that there is no way to use shared Tonfotos database or transfer it from one PC to another. Every new installation will have to go thru the indexing process and create its own database, this cannot be avoided.
With that said, there is nothing tricky about app transferring, expecially since you don’t need to transfer the license. Just transfer the files or use same shared resource, install the app on the another PC and start it.
Same with using shared drive from several PC’s - just install on all of them, that is it.
What is tricky is how program will synchronize facial data between copies. Program will do that automatically if all copies are working with the same shared drive. But this will just work, you don’t need to setup anything for that. Here’s how it works: https://community.tonfotos.com/d/186-version-150-people-data-synchronization
To prevent duplicates from getting to your archive you can use Import from folder function. It will put new files to YEAR/DATE folders in your archive, while completely ignoring duplicates during import.
