Thank you Graeme for answering! I have actually done all this. I have tried to follow the installation instructions. The executables have their own PATH. At first I didn't understand what path was but I've learned! It's the Argyll drivers that are in use (Argyll LibUSB-win32 devices). When I work with Argyll in the command prompt I navigate (cd) to the Argyll "bin" directory. I have checked that I'm administrator. I did spotread -? (you wrote "spot read -?") and now the instrument is recognized! *I think problem is solved!* My computer is a Lenovo W520 and it has an inbuilt Huey colorimeter on COM1! The i1 Pro is on COM2. I put the argument -c2 and now it asks me to start reading! I may deactivate the Huey but maybe it's installed again when I restart the computer? This could explain why there is problem also in Linux. I still don't understand why it worked in Dispcal but not direct in in Argyll? Maybe because I have to choose instrument in the GUI before making the reading? Actually I have never understood where the Huey came from (I thought I didn't have a Huey!) but of course it's the inbuilt colorimeter that I never use! I have now made my first profile but it wasn't good and I know why! I will make a new try later. It's easy to make a fault in this process but I will try to get a more foolproof workflow. Thank you again! I will donate to your fantastic program! Best regards and greetings from the southern Sweden where we already have got spring. The Crocus is flowering!
