I have Diva installed on my main DAW. In a song the devices are shown as "Diva(x64)". I copied that song to my laptop to work on it, but for all tracks that had "Diva(x64)" I get a warning that Diva(x64) is not installed on my system (the laptop) - except I know full well it is installed.

If on laptop I add track and assign Diva to it, then it is listed as "Diva" and all is fine.

Why is it installed as Diva(x64) on one machine and "Diva" on another? How do I change the device to Diva(x64) on my laptop (or conversely, change to Diva on my main system)?

I have done a reinstall of Diva on laptop and it installs as Diva, I see no option on installation of calling it Diva(x64)
