Also tried sudo mount -o remount,noexec /tmp, didn't help.

[vrozkovec]

actually, looking now, this may be probably related to this issue: #2609

[ghost]

Same problem, but on a windows 8.1. Though in my case the loading messages screen comes up but does not advance, as in #2642.

[scottnonnenberg-signal]

@konotori A newer version of the product should fix your problem.

@vrozkovec This is probably the closest issue to what you're seeing: #2610

[vrozkovec]

Actually, I have made a mistake before, copied wrong command. If I go mount -o remount,exec /tmp, app works.

[scottnonnenberg-signal]

Alright, I'll close this then.

I'm not very comfortable with marking /tmp as executable

@balping you can also set TMPDIR to something other than /tmp before starting signal-desktop
