It is possible to alter the default location by setting up AGISOFT_REHOST_PATH environment variable prior to the license activation. On macOS - /Library/Application Support/Reprise/agisoft/photoscan-pro/

On Linux - /var/tmp/agisoft/photoscan-pro/ On Windows - C:/ProgramData/Reprise/agisoft/photoscan-pro/ The default location of the 'rehostable' directory differs depending on the OS used: It is used later to validate the available license and stores the system parameters, that why it is important to deactivate the license before applying any major changes to the system, such as OS upgrade/re-install or hardware components replacement.

Here's the reply from agisoft support: Please note that during the license activation of node-locked license an additional so-called 'rehostable' directory is created. I encountered an issue the licence becomes invalid and cannot be deactivated.
