I downloaded winetool and have it in my tmp directory. I can get into the winetools directory by clicking on the folder. But when I read the install instructions it says:

To install WineTools extract the archive in a temporary directory and call
"./install" as user "root". WineTools will get installed at
/usr/local/winetools.

There is an install icon there so I doubled clicked on it because I read somewhere if there was Install file all you had to do was click on it. The terminal window very briefly flashed. So I went to the /usr/local and see no wine tools folder.

When I cd I can get to $tmp but I can't get into the winetools folder.

So doing a step by step what should I do?

You must use a terminal and issue "./insta;;" or whatever your instructions tell you. Do not double click the install instructions or script, that is MS, not linux.
