No, as far as I can see in my case, the problem with the launcher is that it does not check sufficient disk space prior downloading. It run the C: Drive full leaving the system unstable. Also the Download dir cannot be changed after.
I'll give it another try installing the launcher on D:
that is also correct
it thought it needed several gb more than was on my drive, yet it did not tell me this or stop.
it went through its motions only to finally stop and tell me it needed more space.
so I made more space, 20gb extra....and then it finished using less than 1gb.
it actually had the space, it seems to have calculated as though I had nothing installed...It also tried to install to the wrong directory.
all normal for the launcher...
it has always been off center, long ago I started saving it to a special folder, then I make sure it does what it is supposed to do.
But then I do that for all software, I refuse to let any dev decide where things go on my computer. That's my job. its my pc.
and funnily enough, I don't put anything on C:, ever, only the O.S.. that's just asking for problems.
you can change the directory
