Audio file not transferring

I am using Cubase 10.5 on my PC with absolutely no problems.
BUT…I have installed the same Cubase version on my laptop and when I try to transfer an audio track to a new project on the the laptop it comes up with the message, OPENS WITH ADOBE ACROBAT. The file extension is still showing ‘.CPR’ but in upper case! It asks the usual question “open with”, but Cubase isn’t listed as an option.
Does anyone have any idea how to solve the problem…PLEASE?



I’m quite sure, there is an option to choose another application from the location (even on Windows). Please, select the path of Cubase 12.exe file.

Right+click on the file
