Windows 7 Guitar Pro 7.5 not working

Greetings all. I sure could use some advice about my recently purchased Guitar Pro 7.5 that will not work correctly. I downloaded it on my emachines with Windows 7 and it will open but none of the click on icons on home page operate. I go to top of page and drop down the help tab, with same results. I can open a musical notation, however, when it plays is freezes and acts like it's skipping. I have made sure Windows is up to date. I received a couple of error messages when I first downloaded program that I am attaching, but after deleting and reinstalling program a couple of times, the have disappeared. On a hunch, I downloaded program on our laptop that also runs Windows 7 and it works perfectly on it, but I would really like to use it on the emachine set up. I'm not very tech savvy, but I can follow instructions if any suggestions are given.
