Install elsewhere (not main drive)

For Gigapixel 6.x and other 2023 Topaz apps, I want to move the installations and model files to an alternate drive as they are taking up too much space on my SSD main drive. I tried a simple file copy and that failed. I tried adding a symbolic link after the copy and that failed as well. (duh) The installer for the 2023 apps doesn’t include an option for choosing a destination drive. Does anyone here know how to accomplish the goal?

Uninstall the previous version then install the one you have. It will then ask where you want to install not update the current installation.
