Thanks for answering my questions!
For question 1, I download the .exe file to open and set it up, however, after I agreed with the terms and start the setups it displays an error in installing the file which I think is more likely to be unable to access where it needs to download even though the program could also having trouble setting it up in the first place. I don’t have any screenshots though because the problem fixes itself the third time I redownload it. But I thought I should mention it in case anything happens to future installations again. 🙂
