I thought I would give this one more go,I recently downloaded the full linux demo version of guitar pro 6 (r11201). When I first tried to install with ubuntu software centre, I just got "Error" and it failed to install. I tried to install it (with a lot of help from you Guy's) using Terminal but could not get it to install. Someone on the Forum suggested I just double click the file to install, I had already tried to do this as mentioned above, but gave it a go. After several attempts it finally Installed.yah.So now I need to Know how to launch it. I have extracted the files so does anybody know the easiest, most successful way to solve this problem?
This will not be a fix to your problem but more suggestion and my experience. Tuxguitar might not be good option but I believe it's the best software come with more function that I used for my need to learn guitar. It's support .gp3 to gp5 file extension of Guitar Pro.
Just for your consideration. Hope it help with your problem. Thank you.
