TandemVids 2018 is not
backwards compatible. You cannot install a previous version after installing 2018.
If you need to roll back to a previous version, you will need a back up of your current configuration.
To backup the current configuration before installing TandemVids 2018, follow these steps.
1: Create a backup of the data folder. You will need to turn on hidden files to see this folder.
2: Backup this registry key using "Regedit.exe" - see the screenshots.
3: Customer folders for stored projects have not changed but should be backed up or archived as part of your normal procedures.
