@Aravisian , I'll try it again, maybe i should just give it more time.
I am just not familiar with ".run" files in particular, so i didnt know what to think of it, or if clicking on it or letting it run would be a good idea.
These are often also used on WIndows- but this is also not often directly observed by the user. So you are quite correct in your wording: It is unfamiliar. Which means it is well within your capability; just looks new, is all.
With a .run, it can happen that it must download additional necessary files from a repository, which the .run file contains a line to issue that command.
If there is a timeout on that repository (Net connection, packet loss, 404 error, etc) It can hang the whole thing.
This may be what happened when you ran .run (which was an odd sentence to type...)
If you feel you have resolved the issue,
Could you please 'Mark' the post that helped as "Solution".
Or add a post explaining your Solution.
This lets Others know they can find a solution here that may help them.
